To calculate the square footage of a 30x8 foot trailer, multiply the length by the width. So, 30 feet multiplied by 8 feet equals 240 square feet. Therefore, the square footage of the trailer is 240 square feet.
Multiply 37 x 30 to get the square footage.
It is: 16*30 = 480 square feet
390 = 13 x 30
30 feet by 28 feet equals 840 square feet. 30 inches by 28 inches equals 840 square inches, or 5.833 square feet.
540
900 square feet
Multiply 37 x 30 to get the square footage.
900 square feet
It is: 16*30 = 480 square feet

To find the square footage of a rectangular area, you multiply the length by the width. In this case, the area measuring 50 feet by 30 feet would have a square footage of 1,500 square feet (50 x 30 = 1,500).
20 X 30 = 600 square feet.
30 feet x 20 feet = 600 square feet.
105000 square feet
390 = 13 x 30
240 square feet
