Question

The length of a rectangle is twice its width.
If the area of the rectangle is 72 yd?, find its perimeter.

Answer 1

Answer:

Perimeter: 36 yd

Step-by-step explanation:

Length: 2x

Width: x

(2x)(x) = 72

2x^2 = 72

x^2 = 72/2

x = sqrt 36

x = 6

Length = 12

Width = 6

2(12) + 2(6)/= 36 yd
