It depends on the information that you do have.
If you have the base and perpendicular height, the area is 0.5*base*height.
If you have two sides and the included angle, the area is a.b.sin(C)
If you have the three sides (a, b and c) then the area = sqrt[s*(s-a)*(s-b)*(s-c)] where s = (a+b+c)/2
There are other formulae when other measures are known.
What else can I help you with?
How was the area of a triangle found?
Half the base x the height.
How do you find the base of a triangle with the area and height?
It is found by: base = (area*2)/height
What is the area of an equillatoral triangle?
The area of ANY triangle can be found using the formula: Area = Base of triangle * (1/2) * Height of triangle The height of a triangle is measured from the "bottom", or base of the triangle straight up to the top "corner". This measurement is inside the triangle. For example: An equilateral triangle has all 3 sides the same. (See the word equal?) Using your numbers, plug them into the formula and figure out what the area of your triangle is.
Can the area of a triangle be found when only one specified length is given?
Yes providing that it's an equilateral triangle or a right angle isosceles triangle.
What information do you have to know to find the area of a triangle?
You need to know the base and height of the triangle. Once you found these multiply together and divide by two.
The area of a triangle is found by multiplying the length of its base by its height?
No, a triangles area is calculated from base x height / 2
FORMULA- area of equilateral triangle?
Area of Equilateral Triangle A= S2 * (Root 3)/4, where A= Area of the triangle S= Side of the triangle.
A sail has a a spread of canvas as shown in the figurefind the surface area of one side of the sail?
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.
