Question

A gardener is planting a garden in the shape of a square. The gardener wants the side of the square garden to be between 15 and 18 feet long. The gardener wants to put a fence around the garden. How many yards of fencing will be required to enclose this square garden? Remember that 3 feet equals 1 yard. If every yard of fencing costs $1.50, how much will the gardener need to build the fence?

Answer 1

$31.99

Explanation:

The idea begin this problem is to solve for the perimeter of the square garden using the expression for perimeter which is

Perimeter of square= 4L

given that the garden wants the side of the square garden to be between 15 and 18 ft long

Say we go with a length of 16ft (you can pick any number in the range just maintain the formula for the perimeter)

perimeter= 4(16)

perimeter= 64ft

now we have to convert ft to yard

1 yard=3ft

x yard=64ft

cross multiply we have

x=64/3

x=21.33 yards

given that a yard cost $1.5, therefore 21.33 yards will cost

=21.33*1.5

=$31.99
