1 thought on “c) The breadth of a rectangle is half the length. If the perimeter is 48m, find the area of the rectangle​”

  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
