To find the missing measurement (the bottom side), we can use the formula for the area of a rectangle:
\[
\text{Area} = \text{length} \times \text{width}
\]
Given:
- Area = 81 in²
- Right side (width) = 9 in
We can denote the bottom side (length) as \( b \).
From the area formula, we have:
\[
81 = b \times 9
\]
To find \( b \), we can rearrange the equation:
\[
b = \frac{81}{9} = 9
\]
So the bottom measurement is 9 in.
Therefore, among the given options, the correct answer is:
**9 in**
\[
\text{Area} = \text{length} \times \text{width}
