# What is the length of a rectangle with width?

## What is the length of a rectangle with width?

To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

## How do you find the width of a rectangle if the length is given?

The area of a rectangle is found by multiplying the length by the width. The length is 12 cm and the width is 7 cm. Therefore the area is 84 cm2.

## How do you find the length of a rectangle when given the width?

Substitute the value of width in the formula of the perimeter of a rectangle and simplify the value of length ‘l’, that is, P 2 (l + A/I). l 4 units (or) 2 units. Substitute the value of the length ‘l’of the rectangle in the equation w A/l and simplify to find the width ‘w’.

## How do I find the length of a rectangle?

For example, say the area is 12 square inches, and the width is 3 inches. The length can be found by 12/3 4 inches for the length. area length x width therefore length area /width.. Example: The area of a rectangle is 100 cmxb2.

## How do you find length when given area and width?

In other words, the area of a rectangle is the product of its length and width. That is, A l x w where l is the length and w is the width of the rectangle. For example, the area of a rectangle of length 35 m and width 25 m is 35 times 25 or 875 square meters.

## How do you find width from length?

Substitute the value of width in the formula of the perimeter of a rectangle and simplify the value of length ‘l’, that is, P 2 (l + A/I). l 4 units (or) 2 units. Substitute the value of the length ‘l’of the rectangle in the equation w A/l and simplify to find the width ‘w’.

## How do you find the width of a rectangle without knowing the length?

The length of a rectangle is the longest side, whereas the width is the shortest side.

## How do you find the length when given the width?

To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

## What is the formula to find the length of a rectangular?

P 2 (l + A/I). Then substitute the value of the length ‘l’of the rectangle in the equation w A/l and simplify to find the width ‘w’. Let’s learn through an example how to find the length and width of a rectangle.

## How do you calculate length?

In the same way, if the perimeter and the width are known, the length can be calculated using the formula: Length(L) P/2 – w. Where P perimeter of the rectangle; and w width of the rectangle.

## How do you find length when given area?

To find Length or Breadth when Area of a Rectangle is given

• When we need to find length of a rectangle we need to divide area by breadth.
• Length of a rectangle Area xf7 breadth.
• u2113 A xf7 b.
• Similarly, when we need to find breadth of a rectangle we need to divide area by length.
• Breadth of a rectangle Area xf7 length.

## How do you find the width if you only have the length?

To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

## How do you find the width?

Measure one of the two shorter sides. Because a rectangle has a two sets of congruent sides, it does not matter which side you measure. This is the width. If you know the area and the length but not the width, you can also find the width by dividing the area by the width

## How do you find width with length and height?

How would I find width when I’ve been given volume, height, and length? You divide the volume by the height and the length. You could multiply the height and the length with each other first before dividing. W V / (H*L)

## How do you find the perimeter of a rectangle without the length and width?

Measure one of the two shorter sides. Because a rectangle has a two sets of congruent sides, it does not matter which side you measure. This is the width. If you know the area and the length but not the width, you can also find the width by dividing the area by the width

## How do you find length?

To find the width of a rectangle, use the formula: area length xd7 width. Just plug the area and length of the rectangle into the formula and solve for the width.

## What is the formula to find the length of a rectangle?

Formulas for Arc Length The formula to measure the length of the arc is Arc Length Formula (if u03b8 is in degrees) s 2 u03c0 r (u03b8/360xb0) Arc Length Formula (if u03b8 is in radians) s u03f4 xd7 r.

## What is length formula?

If you know the area, you can immediately determine the length of each side, because it’s the square root of the area. The length of each side of the square is the square root of 20, which is 4.47 meters.

## How do you find the length of an area?

To find Length or Breadth when Area of a Rectangle is given

• When we need to find length of a rectangle we need to divide area by breadth.
• Length of a rectangle Area xf7 breadth.
• u2113 A xf7 b.
• Similarly, when we need to find breadth of a rectangle we need to divide area by length.
• Breadth of a rectangle Area xf7 length.

## How do you calculate width and length?

To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

## How do you find length from area?

Because a square has four sides of equal length, the area is given by A L2. If you know the area, you can immediately determine the length of each side, because it’s the square root of the area. The length of each side of the square is the square root of 20, which is 4.47 meters.

## How do you find the length of one side given the area?

Correct answer: The area of any quadrilateral can be determined by multiplying the length of its base by its height. Since we know the shape here is square, we know that all sides are of equal length. From this we can work backwards by taking the square root of the area to find the length of one side.
