Question

A rectangular enclosure 40 ft long and 20 ft wide is to be built using fencing priced at $1.50 per foot, plus 6% sales tax. How much will the fencing cost?

Answer 1

first, we found the perimeter of the enclosure:

$P=2l+2w=2(40)+2(20)=80+40=120\text{ ft}$

this is the quantity of fence, the total price is:

$\text{Price = 120}\times1.50=180\text{ }$

plus 6% sales tax:

$tax=180\times0.06=10.8$

therefore the fencing cost is:

$180+10.8=190.8$

answer: $190.8
