Question

A farmer has decided to divide his land area in half in order to plant soy and corn. Calculate the area of the entire area so he knows how much soil is needed.

Each bag of soil covers 20 square yards. How many bags should the farmer purchase?

Answer 1

well, using the equation
(top+bottom)/2*height
you get 54, and like in the picture, divide that by two to get 27
the farmer should buy two bags of corn, and two bags of soy, and will have quite a bit left over

Answer 2

the answer is two and i know this because i just took the exam. btw, the area of this shape is 69 units squared so you only need two bags! hope this helps :)
