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.

Answer:
12 dollars
Step-by-step explanation:
He spent 3/7 of 56
3/7*56 =24
Take the original amount and subtract what was spent
