Question

The ratio of length and breadth of a room is 4:3 if the room is 12m long find its breasth

Answer 1

Step-by-step explanation:

length: breadth =4:3

4x is equal to 12metre

x is equal to 12/4metre

3x is equal to 3×3metre

breadth =9metre

Answer 2

To find : breadth of room.

Given : length of room = $12\ m$

Solution :

• As per the given data we are given that ratio of length and breadth of a room is 4:3 .
• Let  breadth be $x$.
• Therefore, we write as , $\frac{l}{b} = \frac{4}{3} = \frac{12}{x}$
• Solving for $x$, we take variable at LHS and constants at RHS.

                     $x = \frac{36}{9}$

                     $x = 9$

Hence , breadth of room is $9m$,
