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 bredth of the rectangle.

Answer 1

Let the length and breadth of the rectangle be 3x m and 2x m respectively.
so perimeter of the rectangle =2 (3x+2x)m
=10x m.
by the condition,
2×10x =120
=>x=6
so, breadth of the rectangle is 3×6m i.e. 18m.
hope it helps you...
