Simple. Just multiply the base by the height of the triangle, and divide it into two. This works for all types of triangles.

how to find the perimeter of a right angled triangle using the area
to find the area of any triangle follow the formula: 1/2(b*h) "B" - stands for the base of the triangle "H" - stands for the height of the triangle
The area of a right-angled triangle with base 8 cm and hypotenuse 10 cm is: 24 cm2
If it is a right triangle, you can use the Pythagorean theorem to find the height since it will be on of the sides. If it is an equilateral triangle, you can break it up into two right triangles and use the part above. If it is an oblique triangle, you use the angles and some trigonometry to find it. Since the area is 1/2 b x h, if you are given the area, you can solve for the height.
Area of a right triangle = (1/2 the length of one leg) x (length of the other leg)
