Question

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

Answer 1

Area of the rectangle = 12 x 4 = 48 ft²

Area of at the missing part = 3 x 2 + 1 x 2 = 8 ft²

Area of the hole = 48 - 8 = 40ft²

Answer 2

8ft² (Missing part: 6ft² plus Inside Hole: 2ft²)

Explanation:

It's necessary to remember that the Rectangle Area formula is equal to Base Area times Height and its outcome is given in ft².

Let's call the missing part, the upper one is a rectangle A=2x3 A=6 ft².

The hole area is 2ft² (another rectangle whose area = 2 x 1 ft². The missing part plus the hole part completes the Outdoor Carpet, whose area should be a bigger triangle 48ft².
