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
