Help how do you calculate the area of a triangle?

[Anders1]

I'm in the process of replacing the panel on our house. What I'm interested in is how to calculate how much panel is needed for the gable peaks, in other words, how many square meters it is. I remember that you can calculate width times height and then divide it by 2, am I on the right track or is it completely wrong? Grateful if someone can help me

That's correct, the area of a triangle is the width times the height divided by two.

PS
Misleading subject line!
You want to calculate the triangle, not the square... hehe

The area of the entire gable peak is the entire width of the gable x the height of the peak divided by 2, so you remember correctly. If you draw on grid paper and draw a vertical line from the peak downwards, you'll understand why.

The area of all forms of triangles is the width of the base times the height perpendicular to the base divided by two, not just for isosceles.

It gets trickier when you have mansard..

Thank you

But you have two gables, so the width times the height will give you material for both sides! ;-)
