If a square has an area of 49 square units, what is the length of its side?
Given that area the square is 49 square units and we are going to find the length of its side as follows
Lel the length of the side of square is denoted by s
We know that area of the square = (length of the side)2
Now area of the square = s2
49 = s2
Then by taking square root both side we get
s = the square root of 49
s=7
Therefore the length of the side of the square is 7 units.
