Question

if the breadth of is one third of its length and if perimeter is 80 c.m.find the length and breadth of rectangle

Answer 1

Answer:

length and breadth of rectangle are 30cm and 10cm respectively.

Step-by-step explanation:

Let length be L, then breadth is L/3

Perimeter = 80

or, 2× (L+B) = 80

or, L + L/3 = 40

or, 4L/ 3 = 40

or, L = 30

So, Breadth = L/3 = 30/3 = 10
