Answer 1) For the area of a square we should choose a perfect square number so that we can find its side by finding square root of the area because area of square = side ×side =side²
2) We need to find the square root of the area of the given square to find the side length of the square.
side=√area of square
3) No , it is not possible to find a side length that would be perfect for a square with an area of 45 square units as if we find its side we need to find its square root i.e.
................>where√5=2.236 is irrational
Therefore side=3×2.23.... = 6.708...... unit → which is not accurate we have to take approx value of it to get the side length of the square.
