To find out how much of the rectangular area Carl can complete in 1 hour, we start with the information given:
Carl completes \( \frac{2}{5} \) of the area in \( \frac{1}{2} \) hour.
To determine how much area Carl can complete in 1 hour, we can first find out how much he completes in 1 hour by doubling the amount he completes in \( \frac{1}{2} \) hour:
\[
\text{Area completed in 1 hour} = 2 \times \left( \frac{2}{5} \right) = \frac{4}{5}
\]
Thus, Carl can complete \( \frac{4}{5} \) of the area in 1 hour.
