It seems like there's a missing image or specific values for the length and width of the rectangle in your question. However, if the length and width of the rectangle are given as rational expressions, the area A can be found by multiplying the length and width.
Let's say the length is L) and the width is W, both represented as rational expressions. The area formula is:
![\[ A = L \cdot W \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/6ledqelfb5kyq978v3dneqneagf3ybcwx8.png)
If
and
, where a, b, c, d are integers, the area expression is:
![\[ A = \left((a)/(b)\right) \cdot \left((c)/(d)\right) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/zp3f3yb3dx0hyt89nzcs3i3dt1me2tfwyr.png)
Simplifying this expression would depend on the specific rational expressions given for length and width.
For example, if
and
, then:
![\[ A = \left((2)/(3)\right) \cdot \left((5)/(7)\right) = (10)/(21) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/gldhwqyt51hs24g4kuw8q9u246w53hnxqi.png)
So, the rational expression describing the area is
