Solution:
Square A Area = 9 cm²
Area of square = side²
=> side² = 9
=> side = 3 cm
Perimeter of Square = 4 x side
Perimeter of Square A = 4 x 3 =12 cm
Side of Square B = 2x 3 = 6 cm
Perimeter of Square B = 4 x 6 =24 cm
Area of Square B = 6² =36 cm²
Area of Square B / Area of square A = 36/9 = 4
Perimeter of Square B / Perimeter of square A = 24/12 = 2
