Find the missing measurement. Round your answer to the nearest tenth.

Question

bottom= ? in
right = 9 in
Area = 81 in^2
Question 8 options:

9.2 in

6.5 in

9 in

5.4 in

Answer 1

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
