Answer 2

Answer:

Step-by-step explanation:

First the room is in rectangular shape

So,

The area of room = area of rectangle

Area of room = 154/10 sq.m

Breadth of a room = 21/20m

According to the problem

Area of the room = L × B

154/10 = L× 21/20

15.4 = L × 1.05

15.4/1.05 = L

14.6666667 = L

Length = 14.6666667

(Or)

= 44/7

Both are same
