Question

To landscape your yard, you use stones that are in the shape of a triangle. Each stone has a base of 12 inches and a height of 6 inches. How much area will 9 stones cover?

Answer 1

I'm not entirely sure about this but here is my approach:

Area of a Triangle: ½base×height

Area of Triangle = ½(12×6)

= 36

Area of 9 Triangles: 36×9

= 324
