Question

Nicholas is covering a triangular area with mulch. The base of the area is 22 feet, and the height is 10 feet. One bag of mulch covers 8 square feet.

How many bags of mulch does Nicholas need??

1. 13 bags
2. 14 bags
3. 28 bags
4. 40 bags

Answer 1

14 bags

Explanation:

Answer 2

14 bags

Explanation:

First find the area of the triangle, which is 1/2bh=A, so if you put the base and the height is it would be 1/2(22*10)=A or 1/2(220)=110. So the area is 110ft^2. If you then divide 110/8 to find out how many 8 ft^2 are in 110 ft^2 you get 13.75.
