To calculate the area of the rectangle, we first need to ensure all measurements are in the same unit. Since the length is already in feet, we'll convert the width from inches to feet:

Conversion:

1 foot = 12 inches.
So, $30 \, \text{inches} = \frac{30}{12} \, \text{feet} = 2.5 \, \text{feet}$.

Area of a Rectangle Formula:

$\text{Area} = \text{Length} \times \text{Width}$

Substituting Values:

$\text{Area} = 5 \, \text{feet} \times 2.5 \, \text{feet} = 12.5 \, \text{square feet}$

Final Answer:

The area of the rectangle is 12.5 square feet.
