Question c) The breadth of a rectangle is half the length. If the perimeter is 48m, find the area of the rectangle

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 Reply
