K, well there is no surface area of a triangle, because a triangle is a 2s figure. Surface area is for a 3d figure. To find the regular area of a triangle the formula is 1/2 of the base X the height :) gl :P
the formula for the area of a triangle is: base times height divided by two.
Area of triangle * 2 + perimeter of triangle * length.
The formula for the surface area of a circle is pi times the square of the radius. The formula for the surface area of a triangle is base times height, divided by 2. The formula for the surface area of a square or rectangle is length times width.
use the formula. ti
The formula for the area of a triangle is base times height, divided by 2. The base is one of the sides and the height is a perpendicular line connecting the base to its opposite point.
You need to calculate the area of the base (square), and the area of one triangle, and multiply that by 4.
Assuming the cross-section is an equilateral triangle with sides of 'a' and the length is 'b' the surface area will be 3ab + SQRT(3).a2
Assuming that a sail is a triangle shape, the area of a triangle can be found by using a simple formula. Half the base or bottom multiplied by the height of the triangle and its tallest point will give surface area.
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.
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
