Where should I start with this program?

I am taking Comp Sci I at my high school. I have been having trouble recently because we are focusing on OOP now. The final exam is tomorrow, and it would be much appreciated if y'all could help out:

**Write a simple class for a triangle.**

A triangle has side lengths.

Constructors (default and initialization)

Accessors

Modifiers

Method to calculate the area (find the area of one side height times width then multiply by six)

toString to output height, base, and area
