Question

the length and breadth of a room are in the ratio 7:6. Find the length if the breadth is 12m

Answer 1

ratio length/breadth=7/6 and breadth is 12m
then,
length/12=7/6
so length=14m

Answer 2

Given that length and breadth are in the ratio 7:6

Let the length be 7x and breadth be 6x

Measurement of breadth is given as 12m

Then 6x = 12 , x = 2

Therefore length is 7x = 7 × 2 = 14 m
