## How do u find a perimeter of a rectangle?

To find the perimeter of a rectangle, add the lengths of the rectangle’s four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.

1 Expert Answer In this case, the perimeter we know is 64 feet.

### How do I find the perimeter and area of a rectangle?

The perimeter P of a rectangle is given by the formula, P=2l+2w , where l is the length and w is the width of the rectangle. The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width.

How do you find the length of a perimeter?

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.

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

A = length × width = a × b A = length × width = a × b. 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.

What is the distance around a rectangle called?

The distance around a rectangle is called the perimeter of the rectangle. It is usually denoted by P P. 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
