Exercise 36 Page 600

To find the area of the square, we will use the formula for calculating the area of a rectangle. Since a square is a rectangle whose length $\ell$ and width $w$ are equal, we can adapt the formula for a square with side length $s.$ We have been given that the side length $s$ is equal to $5\text{ cm}$ To find the area of the square, we will substitute this value into the formula to calculate $A.$ The area of the square is $25{\text{ cm}}^2.$
