Question

You just bought a dog, so you want to install a fence around your yard. The yard is rectangular and is 35.8 feet wide by 55.2 feet long. Each foot of fencing costs $4. How much is the fence going to cost you?

Answer 1

$728

Explanation:

We answer this by finding the perimeter of the yard in feet and multiplying that result by the unit cost of the fencing material:

Total cost = Perimeter times Unit Cost

= { 2(35.8 ft) + 2(55.2 ft) } * ($4/ft)

= { 182 ft)*($4/ft) = $728
