There are many ways to find the area of a triangle depending on what information you have
Area = 1/2 x Base x Perpendicular Height
Area = 1/2 x Side 1 x Side 2 x sine(angle between those two sides)
There are many more if anyone cares to add them but these are the most commonly used ones

Here's one that I have used many times:
Given sides of lengths a, b and c (no angles), let s = (a+b+c)/2
Then
Area = sqrt[s*(s-a)*(s-b)*(s-c)]
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.
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
Area of a triangle = 0.5*base*perpendicular height
how to find the perimeter of a right angled triangle using the area
To find the area of a triangle you - Half the base then times it by the height ! Alisha xx

Area of a triangle = 1/2*base*height
you split your shape in half, (The rectangle and the triangle), by putting a line through it and then calculate the area of the rectangle and then calculate the area of the triangle, half the area of the triangle then add the area of the triangle and the rectangle together!Then you should have your answer!
Area of a triangle in square units = 0.5*base*height
