Question

A rectangle has an area of 524.4m2.
One of the sides is 6.9m in length.
Work out the perimeter of the rectangle.

Answer 1

Breadth= Area/Length
524.4/6.9
=76

Perimeter=2(l+b)
2(6.9+76)
2(82.9)
165.8 answer

Answer 2

Answer:

p = 168.5m

length = 6.9m

area = 524.4 m^2

using the formulas

A = wl

p = 2(l+m)

solving for p

p = 2 l +2 A/l = 2•6.9+2•524.4/6.9 = 165.8 m
