Question

The perimeter of a square is double that of a rectangle. If perimeter of the square is 120 m, and length and breadth of the rectangle are in the ratio 3 : 2, find the breadth of the rectangle.

Answer 1

2{ perimeter of square}=perimeter of rectangle

(side×side). =2( 2(l+b))

120 = 2(2(3x+2x))

120=2(2(5x))

120,m=2(10x)

120m=20x

120/20=X

6=x

breadth of rectangle =2×6=12m

I hope it is right
