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}*1.50=180\text{ }`

plus 6% sales tax:

`tax=180*0.06=10.8`

therefore the fencing cost is:

`180+10.8=190.8`

answer: $190.8
