This apparent wind needs to be at a "sensible" ,angle, to the boat - enough lateral component that it can still "push" the sail. The lower the drag on the boat, the further downwind this optimum lies. The AC72 used in the America's Cup reached speeds in excess of 40 knots in a 20 knot wind; at that point the apparent wind ,angle, was 19 degrees although the boat is nominally on a broad reach.

Step 2 – The formula to calculate Area of a triangle is: [where s = ] [a, b, c are the length of three sides AB, BC and AC]. Step 3 – Substituting the respective values: Step 4 – Hence, The Area of the triangle is 39.19 cm. Step 5 – As we know, the formula to find perimeter of a triangle is: Perimeter = a + b + c, where a, b, c are the given sides of the triangle.
