  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~ :)
