# How do you find the length of each side of a rectangle with a given perimeter?

## How do you find the length of each side of a rectangle with a given perimeter?

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 length of a rectangle if the area is given?

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

1. When we need to find length of a rectangle we need to divide area by breadth.
2. Length of a rectangle = Area ÷ breadth.
3. ℓ = A ÷ b.
4. Similarly, when we need to find breadth of a rectangle we need to divide area by length.
5. Breadth of a rectangle = Area ÷ length.

What is length in rectangle?

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

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

Let’s discuss how to find length or breadth when area of a rectangle is given.

1. When we need to find length of a rectangle we need to divide area by breadth.
2. Length of a rectangle = Area ÷ breadth.
3. ℓ = A ÷ b.
4. Similarly, when we need to find breadth of a rectangle we need to divide area by length.

### What is the side length of a rectangle?

A rectangle is composed of two sides: length (L) and width (W). The length of a rectangle is the longest side, whereas the width is the shortest side. The width of a rectangle is sometimes referred to as the breadth (b).

How do you find the length and width of a rectangle if you only have the area?

To calculate the length and width of a rectangle first, calculate the value of width ‘w’ by using the area of rectangle formula that is, ‘w = A/l’.

## How do I find the length and width of a rectangle if I have the area?

A = L * W, where A is the area, L is the length, W is the width or breadth. NOTE: When multiplying the length by the width, always ensure you work in the same unit of length.

## How to calculate the length and width of a rectangle?

Online calculator to calculate the dimensions (length and width) of a rectangle given the area A and perimeter P of the rectangle. The formulas for the perimeter P and the area A of the rectangle are used to write equations as follows: P = 2 * L + 2 * W A = L * W

What is the formula to find the perimeter of a rectangle?

To find the perimeter of rectangle we add the lengths of its sides. Thus, the perimeter of a rectangle with the length of a a and the width of b b is P = a + b + a + b = 2 × a + 2 × b = 2 × (a + b) P = a + b + a + b = 2 × a + 2 × b = 2 × (a + b)

### What units are used to measure the area of a rectangle?

In other words, the area of a rectangle is the product of its length and width. The perimeter is measured in units such as centimeters, meters, kilometers, inches, feet, yards, and miles. The area is measured in units units such as square centimeters (cm2) (c m 2), square meters (m2) (m 2), square kilometers (km2) (k m 2) etc.

### What is the definition of width and length in math?

width = length = diagonal = Formulation of Problem Let P be the perimeter of a rectangle and A its area. Let W and L be, respectively, the width and length of the rectangle.
