The area of a triangle is equal to (1/2)base times height. In this case, take the base to be the length of the sail along the horizontal direction and the height to be the mast height. If we measure those in meters, and multiply ir out, we get the area of the sail in square meters.
If the base of the triangle sail and the height are given in metres using the formula, Area = (1/2)(Base * Height) the area can be calculated in sq metre
The area of a triangle can be found by multiplying the height, which is the dimension from the tip to the base at a right angle to the base by half the length of the base. When you multiply the height in meters by one half the base in meters you get square meters of area.
The area of a triangle sail in sqaure meters is calculated as follows: you basicly measure the length of the horizontal and the verical sides and multiply them by eachother. Then you divide them by two.
