Perimeter of a Rhombus Lesson
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.
Perimeter of a Rhombus Example Problems
Let's go through a couple of example problems together to practice finding the perimeter of a rhombus.
Example Problem 1
Find the perimeter of a rhombus with a side length of 10.
- 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.
Example 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?
- 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.
