We have to solve for the long diagonal.
Upper half of long diagonal^2 = 10^2 -8^2
Upper half of long diagonal^2 =100 -64
Upper half of long diagonal^2 =36
Upper half of long diagonal = 6
Lower Half of long diagonal^2 = 17^2 -8^2
Lower Half of long diagonal^2 = 289 -64
Lower Half of long diagonal^2 = 225
Lower Half of long diagonal = 15
Long Diagonal = 6 + 15 = 21 inches
