Question

Ratio of breadth and length of a hall is $2:5$. Complete the following table that shows some possible breadths and lengths of the hall.

Breadth of the hall(in m)	$10$	?	$40$
Length of the hall(in m)	$25$	$50$	?

Add $3$ more of your choice.

Answer 1

Breadth of the hall(in m)	$10$	$20$	$40$		$12$ $28$
Length of the hall(in m)	$25$	$50$	$100$		$30$ $70$

The ratio of Breadth and length is $2:5$

Let the common factor be $x$

So the breadth is $2x$

The length is $5x$

$\to 5x=50x=102x=20$

So breadth is $20$

$\to 2x=40x=205x=100$

So length is $40$

$\to 12:30=2:5$

They are in the ratio so they are considered to be length and breadth

$\to 28:70=2:5$

They are in the ratio so they are considered to be length and breadth
