The Cosmic Pool company is building a pool in Mary’s back yard. The pool is to be 8ft longer than it is wide and cover 240 squar

Aneli [31]

Answer:

The correct answer is C.

Step-by-step explanation:

Since the Cosmic Pool company's pool's length is 8ft longer than the width, you can immediately rule out choices A and B, since their <em>widths</em> are greater than their <em>lengths</em> by 8, and not vice versa. This leaves choices C and D. The perimeter of a quadrilateral's formula is $2(l+w)$ , which means the length plus the width and multiplied by 2. Using this formula, you can infer that the perimeter is $2(20+12)$ = $2*32$ = 64ft, so choice C is the correct answer.
