Question 1036315
height=h
width=2h
the printable area is 2h-14 (width) and the height is h-10 inches
The product h*2h=2h^2=3600
h^2=1800
h=30 sqrt(2)
Therefore, the printable area is 60(sqrt(2))-14  and 30 sqrt(2)-10
That product is 1800*2-1020* sqrt(2)+140=3740-1020 sqrt(2) sq. inches or numerically 2297.5 sq inches
Check is the sign is roughly 42.4 X 84.8
The height shrinks to 32.4 and the width shrinks to 70.8.  That product is 2293.9 or in the range.
