Assuming the rug is a rectangle, it 108 square feet (12 x 9 = 108)
To get the area of any rectangle or square, you just need to multiply the length by the width.
6 feet
Oh, dude, to find the length of one side of a square rug when you know the area, you just take the square root of the area. So, in this case, the square root of 64 square feet is 8 feet. So, like, each side of the rug would be 8 feet long. Easy peasy, right?
10x12=120
The area of the rug would be 749 ft 3 in.
28.3 square feet
72 square feet
The Length of the rug is seven feet.
6 feet
6 feet.
4.
To calculate the area of an 8x11 rug, multiply the length by the width. Thus, 8 feet multiplied by 11 feet equals 88 square feet. Therefore, an 8x11 rug has an area of 88 square feet.
The first part is Area = W*(W + 4) square feet where W is the length, in feet. It is not clear what is required in part B.

The length is 9 feet and the width is 4 feet Check: 9 times 4 = 36 square feet
If one side of a rectangular rug measures 3 feet then its opposite side must also measure 3 feet. Together these two sides measure 6 feet. If you deduct 6 feet from 22 feet then the remaining two sides must measure 16 feet, this means that they are each 8 feet long. A rectangle with sides of 3 feet x 8 feet has an area of 24 square feet.
