Square feet is area, or length times width (L x W), 12 ft x 7 ft = 84 square feet.
12ft 2 in * 7ft 2 in = 121/6 ft * 71/6 ft = 87.1944... sq feet
7 feet 6 inches is 7.5 feet Hence Area = 7.5 x 7 = 52.5 square feet
7 × 3 = 21 square feet
12 x 12 x 6 = 864 cubic feet.
672 cubic feet

7ft by 7ft
630 square feet. Multiply length by width - the result is the area in square feet.
7ft x 7ft = 63ft squared
To find the area of a rectangle, you multiply the length by the width. In this case, the length is 7 feet and the width is 4 feet. Therefore, the area of a 4ft by 7ft rectangle is 28 square feet.
Because six times seven is forty two, there are 42sf (square feet) in a 6x7ft. area.
