It can be any two dimension that, when multiplied by each other, equal 10. It could be 5' x 2', 10' x 1', etc.
5 feet x 10 feet = 50 square feet.
10' x 18' = 180 square feet.
If you multiply feet x feet x feet, you get cubic feet, not square feet.
10' x 12' = 120 square feet.
10' x 18' = 180 square feet.
10 ft x 3 ft = 10*3 = 30 square feet.
12' x 10' = 120 square feet.
10 feet x 10 feet = 100 square feet.
70 x 10 = 700 square feet.
if it is 10 feet X 10 feet it would be 100 square feet.
10 x 12 = 120
The area equals the multiplication of length and width.Accordingly, the area = 7 feet x 10 feet = 70 square feet.
