All quadrilaterals possess four sides --- as the relationships between those sides and the angles between them become more defined, the quadrilateral becomes more specified. A rhombus is a quadrilateral in which each side has the same length. Acting as a link between common quadrilaterals and the more precise shape of the square, a rhombus does not have to have the square's four congruent angles, though its opposite angles must be identical in measurement. By working with the length of just one of the rhombus's sides, finding the shape's perimeter is a simple matter of multiplication.
Instructions
-
-
1
Select one of the rhombus's sides.
-
2
Measure the selected side. For example, say the select side measures 3.5 inches.

3
Multiply the measurement by 4 to calculate the shape's perimeter. For the example, 3.5 inches multiplied by 4 equals 14 inches.
