Question : The length of a side of a square is . If the area of the square is 12, find x. Answer : a re a o f t h e s q u a re = s i d e × s i d e 12 = x × x 12 = x 2 x 2 = 12 x = 12 x = 4 × 3 x = 2 3
Area of square= side*side 12=x∧2 x=√12
The length of the side of the square is 2 3 , derived from the area formula. By setting the area equal to the square of the side, we found x . Simplifying 12 leads to the final answer.
