Area of a Rhombus

Formulas are given below. Note that the diagonals of a rhombus are perpendicular (as is the case with all kites).

Rhombus

s = side length of rhombus h = height of rhombus d_{1} = long diagonal of rhombus d_{2} = short diagonal of rhombus

Area = hs = s^{2} sin A = s^{2} sin B = (½) d_{1}d_{2}
