Understanding how to calculate the perimeter of a rhombus is an essential skill in geometry. This guide will show you step-by-step how to find the perimeter of a rhombus given the length of its sides.
Step 1: Show the Perimeter Formula
The formula for the perimeter \(P\) of a rhombus is given by:
\[ P = 4 \cdot a \]
Step 2: Explain the Formula
In this formula:
- \(P\) represents the perimeter of the rhombus.
- \(a\) is the length of one side of the rhombus.
Since a rhombus has four equal sides, the perimeter is simply four times the length of one side.
Step 3: Insert Numbers as an Example
Let's say we have a rhombus with each side length \(a = 7\) units.
Step 4: Calculate the Final Value
Substitute the value into the formula:
\[ P = 4 \cdot a \]
\[ P = 4 \cdot 7 \]
\[ P = 28 \]
So, the perimeter of the rhombus is 28 units.
Final Value
The perimeter of a rhombus with each side length of 7 units is 28 units.
