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? (4 points)

1 bag

2 bags

3 bags

4 bags

Answer 1

Answer:

54 square yards

It will require 3 bags.

Step-by-step explanation:

The two halves of the field form a parallelogram. To find the area of this shape, multiply the base 6.5 + 2.5 by the perpendicular height 6.

A = (6.5+2.5)(6)

A= 6.5*6 + 2.5*6

A = 39+15 = 54

If each bag covers 20 square yards then to find how many bags you need divided 54 by 20.

54/20 = 2.7

Bags do not come in parts or as a decimal. They come as whole numbers. So 2.7 rounds up to 3.

Answer 2

Answer:

3 bags

Step-by-step explanation:

This is a parallelogram so you find the total area using base times height.

bh = A

b = 6.5 + 2.5 = 9

h = 6

bh = 9(6)

A = 54 square yards

You now know that the total area is 54 yards. 20 times 3 equals 60 square yards so you know that you need at least 3 bags to cover the whole land area.
