1. recall that when lengths of diagonals are given instead of base and height of a rhombus, we can still calculate it's area using the formula
A = (1/2)*(d1 * d2)
where
d1 and d2 are lengths of the diagonals.
substituting,
1326 = (1/2)*(39 * d2)
2652 = 39 * d2
d2 = 2652 / 39
d2 = 68 ft

hope this helps~ :)
