Exercise 36 Page 600

Use the formula for area of a rectangle.

25cm^2

Practice makes perfect

To find the area of the square, we will use the formula for calculating the area of a rectangle. A=l * wSince a square is a rectangle whose length l and width w are equal, we can adapt the formula for a square with side length s. A=l * w ⇒ A=s^2 We have been given that the side length s is equal to 5cm To find the area of the square, we will substitute this value into the formula to calculate A.

A=s^2

s= 5

A= 5^2

Calculate power

A=25

The area of the square is 25cm^2.
