Area of a triangle = 1/2 * Base * Height = 1/2 * 12 * 6.5 = 39 cm2
Use Pythagoras' theorem to find the triangle's altitude or height: 122-62 = 108 and the square root of this is 10.39230485 1/2*base*height = area 1/2*6*10.39230485 = 31.17691455 square units
The square of the length of the base plus the square of the length of the height will equal the square of the length of the hypotenuse of your right triangle, per Pythagoras. Square the hypotenuse, subtract the square of the height, and then find the positive square root of that and you'll have the base of your right triangle.
The general formula for a triangle is Base x Height / 2. That applies quite easily for a right angle triangle.
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.
you can't unless you measure it.
One-half the base.
Only a right triangle has a hypotenuse. An isosceles triangle can be a right triangle but it doesn't have to be. If it's not, then it doesn't have a hypotenuse.
To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle. To find the area of a triangle find the base and the height of the triangle.

the perimeter is 36 and the area is 144
