Answer:

The perimeter is 74 meters

Step-by-step explanation:

By definition the perimeter of a rectangle is the sum of the lengths of its 4 sides.

The formula for calculating the perimeter of a rectangle is as follows:

P = 2w + 2L

Where P is the perimeter, w is the width and L is the length.

In this case we want to find P and we know that:

w =16\ meters

L =21\ meters

Therefore:

P = 2(16) + 2(21)

P = 74\ m
