30ft
A 30ft x 14ft room = 420 square feet.
Since a square has right angles, you can use the Pythagorean Theorem to calculate the diagonal. Specifically, the diagonal of a square is equal to the length of a side, multiplied by the square root of 2.
The formula for the area of a circle is pi*radius^2. So in this case it is PI*30ft^2. 3.14*30*30 = 2827.43
30ft x 90ft = 2,700 sq ft or 250.8382 square meters.
1500 ft2
25.92 feet
You multiply the length by the width, i.e. 47ft x 30ft = 1,410 square feet.
30 ft * 12 ft = 360 sq ft = 33.445 sq metres
How can it be a square if it's 10 x 30 ffs?
30 ft * 17 ft = 510 sq ft = 47.38 sq metres
30 ft * 20 ft = 30*20 sq ft = 600 sq ft
42 ft x 30 ft = 1,260 square ft1 yd = 3 ft(1 yd x 1 yd) = 1 square yd = (3 ft x 3 ft) = 9 square ft.1,260 square ft = (1,260 / 9) = 140 square yards
30ft... You multipy the width by the length
