**Reiny**, Tuesday, March 23, 2010 at 4:52pmso each side is 9 inches.

A property of a rhombus is that its diagonals right-bisect each other

Let the other diagonal be 2y inches, so we have

4 congruent right-angled triangles with sides 7 and y and hypotenuse of 9

y^2 + 7^2 = 9^2

y^2 = 32

y = √32 = 4√2

so the other diagonal is 8√2
