The length of a rectangle is 25 feet. The width is 8 feet. What is the perimeter of the rectangle

Perimeter is found by adding all of the sides together. Since it's a rectangle, you have two sets of two identical sides.

Perimeter = length + width + length + width

P = l + w + l + w

P = 25 + 8 + 25 + 8

P = 66 feet
