Glen,

That's exactly the correct solution.

If one assumes that the building's area is made up of an arbitrary number,
say N, of squares of an arbitrary size, say L, then the total area is A = N
* L * L. To increase A by 125%, you have to increase the area of each
individual square by 125%. In other words, L must be increased by the
square root of 1.25.
