Use Heron's Formula
The formula for the area of a triangle is A=(1/2)BH where B is the base, and H is the height. If it has 3 numbers, pick out the 2 that you need, the base and the height, and use the formula.
Do you mean an equilateral triangle? Then if so then the formula for the area of any triangle: 0.5*a*b*sinC whereas a and b are the embraced sides of angle C And in the case of an equilateral triangle it is: 0.5*any side squared*sin(60 degrees) Alternatively use Pythagoras' theorem to find the altitude of the triangle then use: 0.5*base*height = area
To find the area of a triangle, you use the formula: Area = 1/2 * base * height. Plugging in the values, we get Area = 1/2 * 18 m * 20 m = 180 square meters. Therefore, the area of the triangle is 180 square meters.
To find the area of a triangle, you can use the formula: Area = 0.5 * base * height. In this case, the base is 8cm and the height is 4cm. Plugging these values into the formula, the area would be 0.5 * 8cm * 4cm = 16 square centimeters.

if you know the two legs of the triangle, you can use the Pythagorean theorem to find the hypotenuse as the base. Then you use the formula to find the area of the triangle: 1/2 (pi) bh.
A traingle covers half the area of a rectangle with the same base and [perpendicular] height.
The formula for the area of a triangle is A = ½bh. We can use this formula to find the height, h, of the triangle: 16 = ½*4*h 16=2h /2 /2 8=h The height of the triangle is 8 units.
Ok to find the area of an isosceles triangle: Find the height first, to do this use this formula: Height = Square root ( one side square - half the base square) Now that you have the height you can calculate the area by the use of this formula: Area = (1/2)(base)(height) This will give you the surface area of an isosceles triangle. Lets do an example: You have a triangle that has two sides that measure 24 meters and a base of 20 meters. Using the formula above for height you will get a height of 21.8 meters Now use the formula above to find the area and it will give you an area of 218 meters square
It depends on the size of the triangular prism, but depending on the side of the prism you use the triangle area formula to find it or the rectangle area formula to find it.
The formula for the area of a triangle is A=(1/2)BH where B is the base, and H is the height. If it has 3 numbers, pick out the 2 that you need, the base and the height, and use the formula.
You can use trigonometry to find the height of the triangle. Then just use the well-known formula: area = (1/2) times base times height. You can also use Heron's Formula, which works for any triangle, if you know the three sides.
If you are referring to a right triangle, use Pythagoras' Theorem to find the missing side. Then use the formula for the area of a triangle: area = (1/2) x base x height.
To find the height of a triangle, you can use the formula: height = (2 * area) / base. The base of the triangle is one side of the triangle to which the height is perpendicular. The area can be calculated using different methods depending on the information available, such as using the lengths of the sides and Heron's formula or using the base and the height.
You measure the base and the height. Then use the formula (base*height)/2.
