Area of a Rectangle

Definition of Area

• Area of a shape is a measure of the amount of space inside that shape.

Area of a Rectangle

• The area of a rectangle is calculated by multiplying its length by its width.

  • Formula for Area:

  • The area (

  • A) can be expressed mathematically as:

  • $A = \text{length} \times \text{width}$

Components of the Formula

• Length:

  • The length of the rectangle is defined as one side of the rectangle, which is typically the longer side in a rectangular shape.

• Width:

  • The width is defined as the other dimension of the rectangle, typically the shorter side.

Example Calculation

• Given:

  • Length = 12 centimeters

  • Width = 4 centimeters

• To calculate area:

  • Substitute the values into the area formula:

  • $A = 12 \text{ cm} \times 4 \text{ cm}$

  • Perform the multiplication:

  • $A = 48 \text{ cm}^2$

  • Therefore, the area of this rectangle is 48 square centimeters.

Conclusion

• The area of a rectangle provides critical information for various practical applications such as flooring, gardening, and construction, ensuring adequate coverage.
