Question

The area of rectangular plot is $2400$ squares meters and it's length is $1\frac{1}{2}$ times to it's breadth. What is the perimeter ?

Answer 1

Let $l$ & $b$ be the length & breadth of rectangular

$lb=2400$

$l=1.5b$

$\therefore$ $1.5b^2=2400$

$b=40$

or $l=60$

perimeter $=l+b=60+40$

$=100m$
