# Rhomb calculation

For a rhomb with side length a and diagonals e and f, these formulas hold:

area = (e*f)/2

perimeter = a*4

a = square root of (e/2)^2+(f/2)^2

Arcs are simply calculated by decomposing the rhomb into for rect-angled triangles.

The side length of a rhomb equals square root of ((e/2)²+(f/2)²), als can be seen by Pythagoras.

The area equals e*f/2.

If you want to solve some examples, just enter them above.

For further information just move the mouse over one of the words below. The corresponding part of the rhomb will be marked.
