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
