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.
