Question

If the length and perimeter of a rectangular plot are in the ratio 1:3, then ratio between their length and breadth is

Answer 1

Answer:

the answer is 2:1 ..

let length of rectangle be 'l'm, breadth be 'b'm.

$\frac{l}{p} = \frac{1}{3}$

$\frac{l}{2(l + b)} = \frac{1}{3}$

$3l = 2l + 2b$

$l = 2b$

$\frac{1}{b} = \frac{2}{1}$

therefore required ratio is 2:1
