Introduction
Calculating the area of a rectangle is a fundamental concept in geometry, and it’s crucial for various practical applications, from determining the size of a room to calculating material requirements for a project.
The Formula for the Area of a Rectangle
The area \( A \) of a rectangle can be found using the formula:
\[ A = L \times W \]
Where:
- \( L \) is the length of the rectangle.
- \( W \) is the width of the rectangle.
Step-by-Step Calculation
Let's calculate the area of a rectangle using an example where the length \( L \) is 8 units, and the width \( W \) is 5 units.
Step 1: Identify the Given Values
Given:
- Length \( L = 8 \) units
- Width \( W = 5 \) units
Step 2: Plug the Values into the Formula
Using the formula for the area of a rectangle:
\[ A = L \times W \]
Substitute the given values:
\[ A = 8 \times 5 \]
Step 3: Perform the Multiplication
Now, multiply the length and the width:
\[ A = 40 \]
So, the area of the rectangle is 40 square units.
