Let the rectangle have length L and width W.
Area = Length × Width = L × W.
Therefore the correct option is A.

Understanding the Area of a Rectangle
The area of a rectangle is a fundamental concept in geometry, particularly relevant for students in Class 8.
Formula for Area
- The correct formula for calculating the area of a rectangle is:
- Area = Length × Width
Why This Formula Works
- Dimensions: A rectangle has two dimensions: length and width.
- Unit Squares: The area represents the total number of unit squares that can fit inside the rectangle.
- Multiplication: By multiplying the length by the width, you essentially count how many unit squares fit along the length and how many fit along the width.
Visual Representation
- Imagine a rectangle where:
- The length is 5 units.
- The width is 3 units.
- Visualizing this, you can see that there are 5 rows of squares (length) and 3 squares in each row (width).
- Thus, the total area is 5 (rows) × 3 (squares per row) = 15 square units.
Other Options Explained
- Length + Width: This gives the perimeter, not the area.
- Length ÷ Width: This does not provide any meaningful measurement related to area.
- Length - Width: This also does not yield the area but rather a difference between the two dimensions.
Conclusion
Understanding and applying the formula Area = Length × Width is essential for solving various geometric problems involving rectangles. This knowledge is foundational for further studies in mathematics and its applications.
