The question isn't worded right because you don't have "40x40 square feet." If you are asking how many square feet are in 40 feet x 40 feet, that would be 1600 square feet.
The square root of 1600 is 40. (40x40=1600)
40 x 40 = 1,600 square meters.

It is not possible to answer the question without information about the measurement units used for 40x40. And it is difficult to guess because a 40 inch x 40 inch brick would be huge whereas a 40 millimetre x 40 millimetre brick would be tiny.
40 x 40 = 1600 square feet (can also be written as 1600ft2).
