Question

A sandbox is twice as long as it is wide. It’s area is 72in square. What is the perimeter of the sandbox?

A) 6in
B)8in
C)24in
D)36 in

Answer 1

let the width be 'x'

length = 2x

Area = 72 in square

(2x)(x)= 72

2x^2=72

x^2=36

x=6

perimeter = 2(l+b)

=2(2x+x)

=2(3x)

=2(3*6)

=2(18)

=36 inches

therefore the answer is option D

Hope it helps.............
