Asquare banquet hall has an area of 3600 m. what is the length?

Since the area is 3600m^2, we take the square root of it, which is 60m and 60m is the answer.

Area of square = length × length
= L^2
3600 = L^2
L^2 = 3600
L = square root of 3600
L=60
Therefore, the length of the hall =60 m

The first one is correct
