Here is my solution (EF = 15) to your problem using the diagram you sent me
.
********************************************************************************
from snap shot rhombus AEDF gives us line segments AF, ED, AE, FD are
the same length
********************************************************************************
AE^2 = CE^2 + AC^2 or
FD^2 = (16-FD)^2 + 12^2
FD^2 = 256 + FD^2 - 32FD + 244
32FD = 400
FD = 400 / 32 = 12.5
********************************************************************************
area of rhombus(A) = FD * BD = 12.5 * 12 = 150
note that BD is height of rhombus
********************************************************************************
also A = (1/2) * EF * AD
note AD^2 = AB^2 + BD^2 = 16^2 + 12^2 = 256 + 144 = 400
AD = square root(400) = 20
********************************************************************************
(1/2) * EF * 20 = 150
10 * EF = 150
EF = 15
********************************************************************************
