A garden is in the shape of a square with a perimeter of 68 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 $1.37 per foot, what was the total cost of the fences?

Respuesta :

Answer:

$197.28

Step-by-step explanation:

perimeter of a square = 4 x length

length = perimeter / 4 =  68/4 = 17 ft

Price of the first fence = perimeter x price per foot

68 x 1.37 = 93.16

Perimeter of the second fence = (17 + 2 ) x 4 = 76

total price  = sum of the price of the two fences

Price = 76 x 1.37 = 104.12

total price = 197.28
