Question

The perimeter of a square is double of a rectangle . If the perimeter of the square is 120 m and length and bredth of rectangle are in the ratio 3 : 2 . Find the length and bredth of rectangle .

Answer 1

Let the length be 3x and breadth be 2x.

Perimeter of square = 2(Perimeter of Reactangle)

$120=2\left[2\right(l+b\left)\right]$

$5x=30$

$x=6$

Therefore,

$length$ = $18$ $m$.

$breadth$ = $12$ $m$.
