Find the perimeter of a rhombus.
Understand the Problem
The question is asking for the perimeter of a rhombus, which can be calculated using the formula P = 4a, where 'a' is the length of one side of the rhombus.
Answer
The perimeter is given by the formula $P = 4a$.
Answer for screen readers
The perimeter of the rhombus is given by $P = 4a$.
Steps to Solve
- Identify the length of one side of the rhombus
To find the perimeter, we need to know the length of one side, denoted as $a$. Make sure to verify that you have this value before proceeding.
- Use the perimeter formula
The formula for the perimeter of a rhombus is given by:
$$ P = 4a $$
This means that you will multiply the length of one side by 4.
- Calculate the perimeter
Once you have the value for $a$, plug it into the formula to calculate the perimeter. For example, if $a = 5$, then:
$$ P = 4 \times 5 = 20 $$
The perimeter of the rhombus is given by $P = 4a$.
More Information
The perimeter of a rhombus provides a complete measurement around the shape. A fun fact is that all sides of a rhombus are equal in length, which is why the formula involves multiplying the length of just one side by 4.
Tips
- Forgetting to multiply by 4: Remember that the perimeter requires you to multiply the length of one side by 4.
- Using incorrect measurements: Always double-check that the side length is accurate.
