It's new for me, and i don't even know how should I start.
Break the problem down into parts. First you need to get a triangle. Then you need to calculate the dimensions. How do you get the triangle? The homework problem should tell you. How do you calculate the area of a triangle? Same way as you'd do it by hand -- 1/2 base times height. Break that down further and further and you'll have that part squared away before long. How do you calculate the perimeter of a triangle? Same way as you'd do by hand -- sum of distances between corners. Again, break it into parts and you'll have a program before long. Programmers tend to be reluctant to do other people's homework for them. (People in general are reluctant to do other people's homework for them.) It would help you this week, but you'd be further out of your depth next week and you'd be pretty much bound to fail. Or you'd have a lot more work to catch up and a lot less time in which to do it.
