The area of a rectangle is 42.15 square meters. if the length is 21 meters, what is perimeters of the rectangle?

perimeter = 46.014 meters

Step-by-step explanation:

The formula for determining the area of a rectangle is expressed as

Area = length × width

The area of a rectangle is given as 42.15 square meters. The length of the rectangle is given as 21 meters. This means that the width of the rectangle would be

Width = area/length = 42.15/21 = 2.007meters.

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(length + width)

Perimeter = 2(21 + 2.007) = 23.007 × 2 = 46.014 meters
