Expert Answer:

OUTER WINDOW PANEL AREA TO BE WASHED, might be a good assumption.

Building height, 300 m

Excluding the top and bottom, we have 4 surfaces,

Two, 30x300, and two 50x300.

We can assume each surface area contains 1/4 surface area with window.

Total area of windows to be washed = (1/4)(2x30x300+2x50x300) = 12000 m2
