The sail is in the shape of a triangle, and the problem asks to find the area of the sail.

To calculate the area of a triangle, we use the formula:

$\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}$

From the image, the base of the triangle is 4 meters, and the height is 4.4 meters.

$\text{Area} = \frac{1}{2} \times 4 \, \text{m} \times 4.4 \, \text{m} = \frac{1}{2} \times 17.6 = 8.8 \, \text{m}^2$

Thus, the area of the sail is 8.8 square meters.

Here are 5 related questions to explore:

1. How would the area change if the height was increased by 50%?
2. What is the perimeter of this triangular sail?
3. How would you calculate the area of a non-right triangle?
4. Can you think of a scenario where knowing the sail's area would be important?
5. How does the area formula change for shapes other than triangles?

Tip: In any geometric problem involving areas, make sure to correctly identify the base and height, as they must be perpendicular to each other.
