Question

Sam is building a new deck. His decking material is sold by the square foot. At a cost of $3.90 per square foot, how much will it cost Sam to build a deck that is 18 feet by 14 feet?

Answer 1

The answer is:   $982.80

Explanation

Length of the deck is 18 feet and width is 14 feet.

As the formula for Area is $(length*width)$ , so the area of the deck will be:  $(18*14)feet^2 =252 feet^2$

Now, the cost of the decking material is $3.90 per square foot.

So, the total cost for 252 square feet will be:  $\ 3.90 * 252 =\ 982.80$

Thus, it will cost Sam $982.80 to build a deck that is 18 feet by 14 feet.
