Question

2. The ratio of length and breadth of a room is 3.2. If the sum of length and breadth is 40 m then in
(1) 24 m
(2) 18 m
(3) 16 m
(4) 14 m​

Answer 1

Answer:

Ratio= 3:2

Let the common multiple be x

so, length= 3x

breadth= 2x

According to the given condition

3x+2x= 40

5x= 40

x= 40/5

x= 8 m

length= 3* 8= 24m

breadth= 2*8= 16 m

Answer 2

Step-by-step explanation:

let ratio constant = x

3x+ 2x= 40

5x = 40

x= 40/5= 8

so breadth= 8"2= 16

length= 8*3= 24

you can now find any length by this
