4) A garden is in the shape of a square with a perimeter of
56 feet. The garden is surrounded by two fences. One fence is around the perimeter of the garden, whereas the second fence is 2 feet from the first fence on the outside. If the material used to build the two fences is $1.21 per foot, what was the total cost of the fences?

It costs $ to build the fences.

It costs $154.88 to build the fences.

Step-by-step explanation:

Perimeter of square =

We are given that A garden is in the shape of a square with a perimeter of  56 feet.

So,

Side =

So, Side of square park = 14 feet

One fence is around the perimeter of the garden, whereas the second fence is 2 feet from the first fence on the outside.

Outer length = 14+2+2=18 feet

So, Perimeter of outer fence =

Cost of fencing 1 foot = $1.21

Cost of fencing 56 feet =

Cost of fencing 72 feet =

Total cost = 67.76+87.12=154.88

Hence It costs $154.88 to build the fences.

answer: 140
