A square is a parallelogram with four equal sides and 4 equal angles at 90 degrees each. Since the sides are equal you can denote it as the letter s.
A= s2 (Area of the Square which is sxs)
Note: A raised to the power 1/2 is the same as the square root of A (Area)
Now the area is 24.83 square inches.
Therefore the value for one side s = (24.83sqin)1/2 = 4.98297in = 4.98in approximately.
