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

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

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:
