## How do you find the length and width of a rectangle when given the 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 dimensions of a rectangle when the perimeter is given?

Finding the dimensions of a rectangle given the perimeter and a

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

Dimensions for a Rectangle

Write down the area equation: A = L * W where “A” stands for the area, “L” stands for the length and “W” stands for the width of a rectangle. Solve the area equation: 30 = L * 6. Divide both sides of the equation by 6, and write down the answer. It will look like this: 5 = L.

## Which formula shows how the length of a rectangle can be determined from the perimeter and the width?

The formula for find the perimeter, P, of a rectangle with length l and width w is given. P = 2l + 2w. Which formula shows how the length of a rectangle can be determined from the perimeter and the width? A) l = P÷2- 2w.
