If it is a right angled triangle then it is 0.5*(base)*(height) of the triangle half the base times by the height imagine it as half the area of a rectangle of the two triangles

That is all very well if you know the base and the height. Sometimes you know only the three sides. Or only two sides and an angle, or two angle and a side. There are a whole host of formulae for such circumstances.

How do you find the area of a rectangle with a triangle attached to the side?
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!
What is the formula to calculate the area of a triangle?
Area = 1/2*base*perpendicular height
How do you work out the area of a triangle inside a square?
If you want to figure out just the area of the triangle, the formula is base times height divided by 2. It does not matter if it is inside a square, as long as you have the legnths of all they sides you need to calculate the area of that triangle. If you do not, It would be very difficult.
What is the area of a triangle with a base of 18cm and a height of 20cm?
To calculate the area of a triangle, you use the formula: Area = 0.5 x base x height. Plugging in the values given, the area of the triangle would be 0.5 x 18cm x 20cm = 180 square centimeters.
How do you calculate the surface area of an equalaterial trinuglar based prism?
To calculate the surface area of the equilateral triangular-based prism, you need to calculate the area of the equilateral triangle and all the other sides of the prism. The total area of all the phases will give the total surface are of an equilateral triangular based prism.
