1. Answer:

   perimeter=48m

   supposing length as x

   then; breath of a rectangle =1/2x

   we know that:

   p=2(l+b)

   48=2(x+1/2x)

   now taking LCM we get;

   48=2(2x+1x/2)

   LCM is as a whole for both part no emphasis in my keyboard

   48=6x/2

   now by cross multiplication method

   48/1=6x/2

   6x=96

   x=16

   length of a rectangle =16m

   breadth of a rectangle=1/2x

   1×16/2

   8m

   breadth of a rectangle =8m
