The formula for the area of a square is: [tex]\text{Area} = \text{side} \times \text{side} = \text{side}^2[/tex]where "side" is the length of one side of the square. This means you multiply the length of one side by itself to get the area.Alternatively, if you know the diagonal [tex]d[/tex] of the square, the area can be calculated using: [tex]\text{Area} = \frac{d^2}{2}[/tex]
