Question

The ratio of the length of a rectangle to its breadth is 2:1. if the perimeter is 72 meter, find the length and breadth of the rectangle

Answer 1

length:breadth=2:1
let length be 2x
Then breadth is x
Perimeter of a rectangle=72 m
2(length + breadth) =72
2x+x=72/2
3x=36
x=36/3
x=12

Length=2x=2(12)=24 m
Breadth=x=12 m

Answer 2

Hi friend, Here is the required answer :-

Let the length of the rectangle be 'x'.
And breadth of the rectangle be 'y'.

According to the question :-
x=2y
x-2y=0...... (1)
2(x+y)=72
2x+2y=72......(2)
Adding (1) & (2),
3x=72
x=24.

Length= 24 m
Breadth = 12.m

Hope this helps you...
