Question

How many square feet of outdoor carpet will we need for this whole?

Answer 1

1/2((6)(3)). (6)(12). 72-9
1/2(18). 72. 63ft squared
9

Answer 2

Explanation:

The green part, I take is what is already covered, not what has to be covered.

The triangle is what you need to find which is given as 9 square feet. So the first statement can't be right.

Here you have to subtract 9 from 72

Area needed = 72 - 9 = 63 square feet.

72 square feet would be the amount with the triangle filled in.

63 square feet is the number of square feet needed with the triangle cut out.
