Question

A rectangular field is $100$ m by $80$ m. Find the ratio of :

i) length to its breadth

ii) breadth to its perimeter

Answer 1

A rectangular field is $100$ m by $80$ m.

$A.$ Length to its breadth

So:

A Ratio of length to its breadth

$=100:80$

$=5:4$

$B.$ Breadth to its perimeter

$b=80$ m

Perimeter $=l+b=2(100+80)=(180{)}^2=360$

$b:p$

$=80:360$

$=2:9$
