Question

A play yard id 36 ft by 21 ft. A fence is to be built around the yard. How many feet of fencing will be needed? If fencing costs $4.25 per foot, what will be the cost of the fence?

Answer 1

perimeter = 2(length + width)

 

P = 2(36 + 21)

P = 2(57)

P = 114

 

The perimeter is 114 ft.

 

Multiply 114 by $4.25 to get the cost of the fence.
