The width should be x cm.

Thus length =3x

Area=1875cm sq

Considering the query,

$3x\times x=1875\phantom{\rule{0ex}{0ex}}{x}^{2}=\frac{1875}{3}\phantom{\rule{0ex}{0ex}}{x}^{2}=625\phantom{\rule{0ex}{0ex}}x=25\text{}cm$

Now, length $=25\times 3=75\text{}cm$

Breadth =25

Perimeter of rectangle =2(l+b)=2(25+75)

2(100) =200cm.ans

Thus length =3x

Area=1875cm sq
