Figure it up I say... $\displaystyle (175+60)(144)-\frac{\pi 60^2}{4}-\frac{\pi 65^2}{2} + \frac{\pi 72^2}{2}$
so how did you figure out the (175+60)(144) part? i understand that the 175 comes from the top, but where does the 60 and 144 come from?
60cm is the radius of circle in the corner, 144cm=2*72cm is the diameter of circle...
oooo okay i get it, thanks alot!
