the breadth be x cm
then the length is 2x cm
Thus area of square= length * breadth
162 = 2x * x
162/2 = x^2
x = 9 cm
breath = 9 cm and length = 18 cm
Perimeter = 2 * (9+18) = 2*27 = 54cm
then the length is 2x cm
Thus area of square= length * breadth
162 = 2x * x
162/2 = x^2
x = 9 cm
breath = 9 cm and length = 18 cm
Perimeter = 2 * (9+18) = 2*27 = 54cm
