Q. The length of a rectangle is ‘l’ and its width is half of its length. What will be the perimeter of the rectangle if the length is doubled keeping the width same?

Option
(1) 4l
(2) 5l
(3) 6l
(4) 3l

• given,
  length=l so width=length/2= l/2
  now length is doubled keeping the width same
  so length= 2*l & width = l/2
  perimeter of the rectangle =2(length+width)=2(2l+ l/2)=4l+l=5l
