A rhombus — a "pushed-over square" with four equal sides — has perpendicular diagonals that bisect each other, and that fact gives the area at once: the diagonals slice it into four right triangles that reassemble into a rectangle of half the diagonals' product, so A=12d1d2A = \tfrac{1}{2}d_1 d_2. Diagonals are usually the easy measurement on a diamond-shaped panel or a lattice opening, which is why this form beats base × height in the field.
