make a sketch

in a rhombus, the diagonals right-bisect each other.

So we get 4 congruent right angled triangles.

By Pythagoras , it is easy to see that each triangle has sides 3,4, and 5

So the other diagonal is 8 units long.

The area of a rhombus is (1/2)(product of the diagonals)

= (1/2)(6)(8) = 24
