<span>Given:
Price = 2$ per square foot</span>
Total price = $288
<span>Find:
The length of the floor in feet.</span>
Solution
Squares have sides of
equal length. The solution for the area of a square is:
<span>Area = x2</span>
where x is the side
length.
If each square foot
is $2 and the total is $288, we divide 288 by 2 to find out how many
square feet the floor has.
$288 / ($2 per square
foot) = 144 square feet
Take the square-root
of this value to get the length of the floor.
x = √144
x = 12
<span>Therefore, the length
of the floor is 12 feet.</span>
