**MathMate**, Friday, April 8, 2011 at 7:21amThink of the rhombus as a rectangle where the lines joining the mid-points are the diagonals of the rhombus.

The area of a rhombus is therefore half of product of its diagonals.

So 15*D/2=165.

Solve for D.

AC and BD diagonals

A=AC*BD/2

165=15*BD/2

2*165=15*BD

330=15*BD Divide with 15

BD=330/15=22

go to wikipedia and type rhombus
