The answer will depend on 24 WHAT!
1 acre = 43,560 square feet 13 acres = 566,280 square feet
234 square feet (18 x 13 = 234)/
30 square yards.
169 square feet. Multiply the length by the width. The result is the area in square feet.
The answer depends on the units used fopr 23 and 13. It should be obvious to anybody tha the square footage of 23 feet by 13 feet will be quite different to that for 23 metres by 13 metres (or any other units of length)!
Multiply 13 x 13, that comes to 169 square feet.
14' x 13' = 182 square feet.
26 square feet.
26-ft x 13-ft = 338 square feet.
9 square feet = 1 square yard Area of the wall (each side of it) = 9' x 13' = 117 square feet = 13 square yards.
13 * 13 = 169 square feet.
If mean how many square feet are in 13 feet by 25 feet, then the answer is 325 square feet. (13 x 25 = 325)
13' x 13' (169 square feet) = 18.77 square yards. (divide square feet by 9 to get square yards)
Its 169 square feet.
if you mean 13 feetx13 feet, then answer is 169 square feet
12 x 13 = 156 square feet.
13 x 20 = 260 square feet.
