    if its not a quiz then what does it matter? Its to learn it and understand it. I understand the situation yoou're in, trust me i've been there dozens of times, but i cant help if i don tknow whats wrong. So, you can open your work folder and I can try to help but I'm going to explain it to understand it, not to get it done quickly.

    Okay so we just use our area formula for it and rearange it. so if our formula was h(bases/2)=A and we dont know the h, we just plug all the other numbers in a solve like an albegra problem.
