To find the area of the poster, you need to multiply the length and the height together.
Given:
- Length of the poster = \( \frac{1}{2} \)
- Height of the poster = \( \frac{3}{4} \)
Now, let's calculate the area:
\[
\text{Area} = \text{Length} \times \text{Height}
\]
Substituting the values:
\[
\text{Area} = \left(\frac{1}{2}\right) \times \left(\frac{3}{4}\right)
\]
To multiply the fractions:
\[
\text{Area} = \frac{1 \times 3}{2 \times 4} = \frac{3}{8}
\]
Avery claims the area of the poster is \( \frac{5}{4} \). Her mistake is in calculating the area. The correct area of the poster is \( \frac{3}{8} \), not \( \frac{5}{4} \).
