How to Easily Find the Perimeter of a Rectangle with Formula & Example

Perimeter of a rectangle

P= 2L + 2w

The perimeter of a rectangle is the total distance around the outside of a rectangle. To find the perimeter of a rectangle, you need to add up the lengths of all four sides.

If the length and width of the rectangle are known, the formula to find the perimeter is:

Perimeter = 2(length + width)

For example, if a rectangle has a length of 5 units and a width of 3 units, the perimeter would be:

Perimeter = 2(5 + 3)
Perimeter = 2(8)
Perimeter = 16 units

Therefore, the perimeter of the rectangle is 16 units.
