A = 706.9 square feet.
30 feet x 30 feet = 900 square feet.
Multiply the two numbers and you get 1,800 square inches. Each square foot has 144 square inches. So you get 12.5 square feet.
30 inches by 10 feet = 25 square feet.
13.93 square meters.
30 X 15 = 450 square feet.
360 square feet
600 square feet. Just multiply length by width - the answer is the square footage.
A square with a thirty foot side length has an area of 900 square feet.
The floor is 30 square feet.So is the ceiling.
12' x 30' = 360 square feet
Multiply width by length to get the area. The answer would be 1800 square feet.
70' x 30' = 70*30 square feet = 2100 sq feet.
900 square feet
Area = 16 x 30 = 480 sq feet
0.7 acre = 30 492 square foot
Assuming that 12 x 12 is 12" x 12" (one square foot), then 30 one-square-foot tiles would cover 30 square feet.
