$$$$

Introduction

When it comes to calculating the area of a rectangle, we need to know the length and width of the rectangle. In this case, we are given the side lengths of the rectangle as $\frac{4}{7}$ and $\frac{2}{9}$ units. To find the area of the rectangle, we can use the formula for the area of a rectangle, which is given by the product of its length and width.

Understanding the Formula for the Area of a Rectangle

The formula for the area of a rectangle is given by:

Area = Length × Width

In this case, the length of the rectangle is $\frac{4}{7}$ units and the width is $\frac{2}{9}$ units. To find the area, we can multiply these two values together.

Calculating the Area of the Rectangle

To calculate the area of the rectangle, we can multiply the length and width together:

Area = $\frac{4}{7}$ × $\frac{2}{9}$

To multiply these two fractions, we need to multiply the numerators together and the denominators together:

Area = $\frac{(4)(2)}{(7)(9)}$

Area = $\frac{8}{63}$

Simplifying the Fraction

The fraction $\frac{8}{63}$ is already in its simplest form, so we don't need to simplify it further.

Conclusion

In this article, we have calculated the area of a rectangle with side lengths of $\frac{4}{7}$ and $\frac{2}{9}$ units. We used the formula for the area of a rectangle and multiplied the length and width together to find the area. The final answer is $\frac{8}{63}$ square units.
