Question

A rectangle is 9 meters long and the area is 72 square meters what is the perimeter

Answer 1

Area = length × width

72 = 9 × width

8 = width (9 × 8 = 72)

pertinter = length + width + length + width

= 9 + 8 + 9 + 8

perimeter = 34

Answer 2

perimeter: 34 m

Explanation:

• length : 9

• area : 72

width * length = area

• width * 9 = 72

• width = 72/9

• width = 8 m

perimeter:

• 2 ( length + width )

• 2 ( 9 + 8 )

• 34 m
