Please give step by step explanation​

Answer 1

Answer:

The length of the room is= 47.5 m

Step-by-step explanation:

342 rupees =342×100 paisa = 34200 paisa

In 60 paisa the area of flooring room = 1 square meter

In 1 paisa the area of flooring room = 1/60 square meter

In 34200 paisa the area of flooring room=(1/60) ×34200 =34200÷60=570 square meter

Now the breadth of the room =12 m

The area of the room = 570 square meter

So the length of the room =570÷12 m =47.5 m
