A = 706.9 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 feet x 30 feet = 900 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.
