Answer
Area = 4275 ft$^{2}$
Cost = $1410.75
Work Step by Step
We must first find the area of the lawn.
Area of a Trapezoid: $A$ = $\frac{1}{2}$$h$($b$ +$B$)
Therefore:
Area = $A$
$A$ = $\frac{1}{2}$(45 ft)(80 ft + 110 ft)
$A$ = $\frac{1}{2}$(45 ft)(190 ft)
$A$ = $\frac{1}{2}$(8550 ft)
$A$ = 4275 ft$^{2}$
Area = 4275 ft$^{2}$
Now we must multiply by the cost per square foot.
Therefore:
Cost = $C$
$C$ = (4275)(0.33)
$C$ = $1410.75
Cost = $1410.75
