The sides of a square is (2x+4) cm The perimeter of the square is 18cm
Work out the area of the square

The area of the square is 20.25 cm²

Step-by-step explanation:

∵ The perimeter of the square is 18 cm

∵ The perimeter of the square = side × 4

→ That means equate 18 by side × 4

∴ side × 4 = 18

→ Divide both sides

∴ Side = 18/4

∴ Side = 4.5 cm

∴ The side of the square is 4.5 cm

∵ Area of the square = side × side

∵ The side of the square = 4.5 cm

∴ Area of the square = 4.5 × 4.5

∴ Area of the square = 20.25 cm²

∴ The area of the square is 20.25 cm²
