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?

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

Since the footrest measures 1.54 square yards, Alice will not be able to cover it completely.

Step-by-step explanation:

Since Alicia wants to cover a footrest in the shape of a rectangular prism with cotton fabric, and the footrest is 14 inches by 11 inches by 13 inches while she has 1 square yard of fabric, to determine if she can she completly cover the footrest the following calculation must be performed:

1 square yard = 1296 square inches

14 x 11 x 13 = X

154 x 13 = X

2.002 = X

2.002 / 1.296 = 1.54

Thus, since the footrest measures 1.54 square yards, Alice will not be able to cover it completely.
