A rhombus is an equilateral quadrangle, which is an equilateral having four sides of equal length. It looks like a diamond.
Its area is the product of its diagonals divided by two. Note that its diagonals are perpendicular to each other, and bisect each other.
In symbolic form, the area of a rhombus having diagonals of lengths D1 and D2 is:
<math>A=\frac{D_1 \times D_2}{2}</math>
This area also equals the length of a side (B) multiplied by the length of the perpendicular between two opposite sides (H):
<math>A=B \times H</math>
