I mean "3 1/2" if you don't get it-
Well if AsubscriptT is total area and SsubscriptT is total length of side (since both sides are the same length), then
SsubT = 7*(3 1/2) = 7*(7/2) = 49/2
AsubT = SsubT*SsubT = (SsubT)^2 = (49/2)^2 = 2401/4 = 600.25, or 600 1/2
:-)
so close ... until that last = sign.
