Answer
Cost per square foot = \$1.60
Work Step by Step
We must first determine the area of the office space.
Area of a Trapezoid = $A$ = $\frac{1}{2}$$h$($b$ + $B$)
Therefore:
$A$ = $\frac{1}{2}$(20 ft)(20 ft + 32 ft)
$A$ = $\frac{1}{2}$(20 ft)(52 ft)
$A$ = (10 ft)(52 ft)
$A$ = 520 ft$^{2}$
Next, to get the cost per square foot we simply divide the total cost by the number of square feet.
Therefore:
Cost = \$832 / 520
Cost = \$1.60
