Question

The area of a rectangle is 259.8m2.if the length is 15 m,what is the perimeter of the rectangle?

Answer 1

Perimeter = 64.64 m

Explanation:

The formulas for area and perimeter for a rectangle are as follows

• Area A = L x W

• Perimeter P = 2(L + W)

where L = length, W = width

Given A = 259.8m² and L = 15m

259.8 = 15 x W

which can be re-written as

15W = 259.8
W = 259.8 / 15
W = 17.32 m

P = 2(15 + 17.32) = 64.64 m
