Answer: About 3
Step-by-step explanation:
Given : A lawn is in the shape of a trapezoid with following dimensions :-
Height : h = 50 feet
Bases : a = 30 feet and b=170 feet
Area of trapezoid is given by :-
Also , it is given that each bag covers 2400 square feet.
Then, the number of bags of fertilizer needed =
Hence, about 3 bags of fertilizer must be purchased to cover the lawn.
