Length of a room is 1.5 times its breadth. If its height be 3.3 m and volume be 495/4 m*m*m, find length and breadth of the room.

Let the length, breadth and height of the room be l, b and h respectively.
First sentence tells you that:
l = 1.5b
Second sentence tells you that h = 3.3 m and the volume is 495/4 m^3
The volume of the room is given by the product of all the three sides, or:
V = lbh
Substitute in the values you have, and you get:
\frac{495}{4} = lb(3.3)
You now have two equations with two unknowns. Find l and b. What do you get? :)
