Area of a triangle = 1/2 * Base * Height = 1/2 * 12 * 6.5 = 39 cm2
The area of triangle is : 18.0
Oh, what a happy little triangle we have here! To find the area, we simply multiply the base (12cm) by the height (6cm) and then divide by 2. So, the area of this lovely triangle would be 36 square centimeters. Just remember, there are no mistakes in art or math, only happy little accidents!
The area of a triangle can be calculated using the formula: Area = 0.5 x base x height. Given the base is 12cm and the height is unknown, the area cannot be determined without the height measurement. To find the area, you would need to know the specific value of the height in order to plug it into the formula and calculate the area of the triangle accurately.
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.
