The figure shows a carpeted room. how many square feet of the room are carpeted?

Multiply 11 with 9

11 x 9 = 99

Area of the whole is 99 ft²

Find the area of the parallelogram that is not part of the rectangle.
Subtract 11 with 6

11 - 6 = 5

Multiply 5 (length) with 5 (width)

5 x 5 = 25
Area of the part missing is 25 ft²

Subtract the whole with the part missing.

99 - 25 = 74

74 ft², or B) is your answer

hope this helps
