Answer:
1725 ft²
Step-by-step explanation:
The formula for the area of a trapezoid is ...
A = 1/2(b1 +b2)h
Here, the bases are given as 65 ft and 50 ft, and the height is 30 ft. Then the area is ...
A = 1/2(65 ft +50 ft)(30 ft) = (1/2)(115 ft)(30 ft) = 1725 ft²
You tell the salesman your lawn area is 1725 square feet.
First deducte his contribution
7,058−7,058×0.70
=2,117.4
Then find weekly deduction
2,117.4÷52
=40.72
