STEALING THE BELL-ROPES.—solution
Whenever we have one side (a) of a right-angled triangle, and know the difference between the second side and the hypotenuse (which difference we will call b), then the length of the hypotenuse will be
a2/2b + b/2
In the case of our puzzle this will be
(48 × 48)/6 + 1½ in. = 32 ft. 1½ in.,
which is the length of the rope.
