a rhombus has an area of 165 square units. Of the lenght of one of its diagonals is 15 units, find the lenght of its other diagonal
I tried DR Russ
I didn't come up with answer of 22 units
could you give more direction
Think 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.
Solve for D.
AC and BD diagonals
330=15*BD Divide with 15
go to wikipedia and type rhombus
