Area of a Square
A square is a rectangle in which the length and width are equal. If the side length is denoted by , then the area of the square is:
When the area is known and the side length is needed, the formula is solved for by taking the square root of both sides:
Thus the side length formula is:
The first formula gives the area when the side length is known; the second gives the side length when the area is known. Because the area must be positive, the principal (positive) square root is used.
