Theory. Rhombus Area

Rhombus is a convex quadrilateral whose four sides all have the same length. Every rhombus is a parallelogram, and a rhombus with right angles is a square.

The formula for calculating of rhombus area:

●

A = a · h

where A - rhombus area,
a - length of rhombus side,
h - vertical height;

●

A = a^{2} sin α

where A - rhombus area,
a - length of rhombus side,
α - angle between rhombus sides;

●

A =

1

d_{1} · d_{2}

2

where A - rhombus area,
d_{1}, d_{2} - length of square diagonal.
