Question

Ratio of length of a rectangle is $3:2$. If the length of the rectangle is $5m$ more than the breadth, find the perimeter of the rectangle.

Answer 1

Ratio of length and breadth of a rectangle $=3:2$
Let length $=2xm$ and Breadth $=2x$
Also, $I$ of rectangle is $5m$ more than the breadth
i.e, $3x=2x+5$
$\Rightarrow 3x-2x+5$
$\Rightarrow 3x-2x=5$
Length $=3x=3\times 5=15m$
Breadth $=2x=2\times 5=10m$
Perimeter $=2$ (Length + Breadth) $=2(15+10)m=2\times 25=50m$.
