To find the area of the triangular sail in George's drawing, we can use the formula for the area of a triangle:
\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \]
Given that the height of the triangle in the drawing is 2 feet and the base is 1 foot, we can plug in these values:
\[ \text{Area} = \frac{1}{2} \times 1 \text{ foot} \times 2 \text{ feet} = \frac{1}{2} \times 2 = 1 \text{ square foot} \]
Therefore, the area of the sail based on the scale drawing is 1 square foot.
