Length of a rectangle is 1 and half time is breadth . if the perimeter of the rectangle is 100cm. find the length and the breadth of rectangle



Let the breadth of rectangle be x
the length of rectangle = 1.5x
perimeter of rectangle=2(length+breadth)
it is given that perimeter=100cm
thus, 5x=100
          x=20 cm 
          =1.5 x 20
          =30 cm
hence the length and breadth of rectangle are 30cm and 20 cm respectively
