Question

perimeter of a rectangle is 2.4 of the perimeter of a square if the perimeter of the square is 40 metre find the length and breadth of the rectangle given that breadth is 1 by 3 of the length ​

Answer 1

Step-by-step explanation:

Let the length of the rectangle be l

then breadth =1/3*l = l/3

perimeter of square =40m

Given that, perimeter of rectangle=2.4 * perimeter of square

2(l+b)=2.4*40

2(l+l/3)=96

4l/3=48

l= 48*3/4

l=36m

b=12m
