Area = 9 cm²

Step-by-step explanation:

Given :

• side = 3 cm

To find :

• Perimeter of Square

• Area of Square

Formulaes :

To find Perimeter of square :

★Perimeter of square = 4 × side

To find Area of Square :

★Area of Square = side × side (a²)

Solution :

Perimeter :

⟶ 4 × side

⟶ 4 × 3
