Since you have the sum of the length of the diaganols you have to make an equation equal to 20.

Assuming the rhombus is ABCD and E is the intersection of the diagonals, then we know the diagonals perpendicularly bisect each other, so AE is half of one diagonal and BE is half the other diagonal. That allows us to solve for x: (x+4) + (2x3) = 20/2 3x + 1 = 10 3x = 9 x = 3 and since BE = 2x  3 = 3 is half of BD, BD = 2*3 = 6 (answer C).
