Question from carolyn, a student: The length of the base of a triangle is twice its height. If the area of the triangle is 100 square kilometers, find the height. |
Carolyn,
- Write down the expression you know for the area of a triangle and set it equal to 100.
- The length of the base is twice the height so b = 2h.
- Substitute 2h for b in the equation in step 1.
- Solve for h.
