The diagonals in a rhombus right-bisect each other, giving you 4 identical right-angled triangles

look at one of them, the hypotenuse would be 15 and the other side is 12.3 , half the diagonal given.

Can you find the missing side using Pythagoras?

Find the area of one of the triangles , then multiply by 4
