measure it with a ruler if there arent any numbers...
you count the number of boxes IN the shape.
Lenght X Width, then you divide the number by 2.
To find the area of a triangle, you have to multiply the base of the triangle and the height of the triangle, then divide the product of those numbers by two.
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. 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.
When you have and obtuse triangle and you are trying to find the Orthocenter
first you would find the base (the bottom of the triangle ). Then you would need to find the length of the triangle (measure the top of the triangle all the way to the top point to the bottom of the triangle) then times the two number than divide the answer times 2 and you should get your answer
In order to find the area of a triangle, you need to multiply the base of the triangle with the height of the triangle and then halve your final answer.The formula is (Base x Height) / 2Using that, the area of a triangle can be found.Hope that helps.Jamz159
To find the length of a triangle or what ever shape your trying to find all you have to do is multiply width times the area. * * * * * Or, if you want the correct answer, you could try to divide the area by the width. That assumes the shape is a rectangle and that the area and width are known!
Area of a triangle = 0.5*base*perpendicular height

To find the area of a triangle you - Half the base then times it by the height ! Alisha xx
