Question

Joni walks once around the edge of the swimming pool. The rectangular-shaped pool is 60 feet long. If Joni walks a total of 176 feet,how wide is the pool?

Answer 1

The total length around the rectangular pool is 176 feet, with the length being 60 feet and width being W.

 

176 feet = 2 x  length (2 x 60 - 120) + 2 x W. Therefore 2W = 176 - 120 = 56 -> W = 56/2 = 28 feet.

 

 

Answer 2

Hi Tracey,

 

The perimeter of a rectangle is 2(L+W)

 

176 = 2(60+W)

and we can solve for W

 

88 = 60+W

W = 28

The pool is 28 feet wide
