I do believe you mean RIGHT triangle when you said perpendicular triangle. A right triangle has two legs and a hypotenuse. The area of a right triangle is 1/2 * (first leg) * (second leg) How do you determine which ones are the legs and which one is the hypotenuse? The hypotenuse is ALWAYS the largest number. So, choose the 2 smallest numbers.
The area of triangle is : 24.0
The area of a triangle can be calculated with one main formula. That is, A=(b*h)/2, where A is the area of the triangle, b is the base of the triangle, and h is the height of the triangle.
If the heights and bases are the same, then the triangle is half the area of the parallelogram.
The area of triangle is : 60.0
