Question

The length of a rectangular field is twice its breadth. If the perimeter of the field is 150 m, find its length & breadth.

Answer 1

Let  breadth of the rectangular field be l cm
then its length =2l cm

Perimeter of the field=150m

∴150=2(2l+l)
=>150=2×3l=6l
=>150/6=l
=>l=25

So length of the field,2l=50cm
     & breadth of the field,l=25cm
