Theory. Perimeter of rhombus

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 perimeter of a rhombus is equal to the product of the length of its side into four.

P = 4a

where P - perimeter of rhombus,
a - length of rhombus side.
