If a room is 9 by 12 feet and you need to know the dimensions of a room that is 2.5 times the size of the room?

All you need to do is multiply each of the dimensions by two and a half. First, multiply each dimension by two, giving you 18 and 24. So that's:
9 x 2 = 18
12 x 2 = 24
Then you need to find half of each of the original dimensions - half of 9 is 4.5 and half of 12 is 6 - and add each result from this calculation onto its respective result from the previous one, like so:
18 + 4.5 = 22.5
24 + 6 = 30.
It'd be a lot easier to explain this if you were here. But basically, this means that the new room would be 22.5 by 30 feet. Hope that helped!

How you can convert photo width and height into centimeter?
You need to know the width and height in some other unit, and then apply the appropriate conversion factor. For example, if you know the dimensions in inches, then multiply each one by 2.54 in order to find the same length in centimeters. If you know the dimensions in feet, then multiply each one by 30.48 . If you know the dimensions in millimeters, then divide each one by 10 . . . etc.
