The name pretty much specifies itself, a sail in the shape of a triangle. lol.
no ...he was not a sailor....
It is called a 'Jib'.
Assuming that a sail is a triangle shape, the area of a triangle can be found by using a simple formula. Half the base or bottom multiplied by the height of the triangle and its tallest point will give surface area.
If a sail is pulled back, it could look like a scalene triangle.
triangle
If the sail is a right triangle (that is, if the angle formed by the base of the sail and the part that runs up the mast is 90 degrees), then the area of the sail is 1/2 times the base times the height.
No, the Mary Celest was not found in the Bermuda Triangle.Actually it was found just outside the Bermuda Triangle.
Right angled, scalene.
The answer is 15.5241747. If rounded, it is 15.5.
The lateen sail looks like a triangle. The point is on one side and the base is on the other side. The base of the sail would be parallel to the main mast. A spar at the top of the sail is attached to the mast. It is mainly used on sunfish and other extremely small sailing craft.

Because your right triangle is half of a rectangle, you would multiply one measurement by the other and then divide that by two. Then multiply that by 15 per square meter. Unfortunately, this will UNDER estimate your cost, as the triangular sail's hypotenuse is NOT a straight line. But it'll get you 'in the ballpark'.
