A lawn is in the shape of a trapezoid with a height of 60 ft and bases of 70ft and 130 ft. How many bags of fertilizer must be purchased to cover the lawn if each bag covers 4000 square feet.
Area of trapezoid = h*1/2*(a+b) ( where a and b are the parallel sides.)
60*1/2*(70+130)
=6000 sq. feet.
1.5 bags will be needed

The answer "1.5 bags is needed" in the post by @mananth is not the answer
to the question posed in the problem.

While 1.5 bags is needed, 2 bags must be purchased, because half of a bag is not sold in stores.


The meaning of this assignment is to teach a student to round a decimal value
in a correct/appropriate way to integer value reasonably and adequately
in accordance with the meaning of the problem.
