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

answer:

36 ft²

Step-by-step explanation:

First you find the area of the entire right triangle.

To do that use the formula A=bh/2

In this case b (base) is 7 ft and the h (height) is 12 ft.

So A = (7)(12) / 2

        = 84 / 2

        = 42

Next you find the area of that little rectangle shape that is cut out of the carpet.

To do that use the formula A=LW

In this case L (length) is 3 ft and the W (width) is 2 ft.

So A = (3)(2)

         = 6

Now because that rectangle is not part of the carpet, we subtract it from the area of the total shape, which is 42.

So 42 - 6 = 36

We will need 36 ft² of outdoor carpet for this hole.

answer:36

Step-by-step explanation:12 times 7 =84 divide by 2 =42-6=30
