Perimeter of a Rhombus

The Perimeter Formula

A rhombus is a quadrilateral with 4 equal sides, a pair of opposing equal acute angles, and a pair of opposing equal obtuse angles.
The formula for perimeter of a rhombus is given as:
P = 4s
Where P is the perimeter and s is the side length.

Example Problems

Problem 1:
Find the perimeter of a rhombus with a side length of 10.

Solution:
Since we are given the side length, we can plug it straight into the formula.
P = 4s
P = 4(10) = 40
The perimeter of the rhombus is 40.

Problem 2:
A rhombus shaped table is measured to have a perimeter of 192 cm. What is the length of one of the table’s sides?

Solution:
Let’s plug the perimeter into the equation and solve for side length.
P = 4s
192 = 4s, s = 192/4
s = 48 cm.
The table’s side length is 48 cm.
