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
d1 = long diagonal of rhombus
d2 = short diagonal of rhombus

Area = hs
         = s2 sin A
         = s2 sin B
         = (½) d1d2
