Answer:

Perimeter of rectangle is 72 feet.

Step-by-step explanation:

We need to find the perimeter of rectangle where

Length = 21 feet

Width = 15 feet are given.

The formula used will be: Perimeter of rectangle = 2(Length + Width)

So, Perimeter of rectangle is:

Perimeter of rectangle = 2(Length + Width)

                                      = 2 ( 21+15)

                                      = 2(36)

                                      = 72 feet.

So, perimeter of rectangle is 72 feet.
