Question 926158: Please help me solve this problem
Find the area and perimeter of a triangle whose vertices are at the points (4,1), (4,9) and (9,5). Enter your final answer as a decimal approximation with at least 2 decimal places. Avoid rounding as much as possible until the very end of your calculation. Don't worry about units.
TIP: Start by drawing a careful graph of the situation described. A picture will help you to think about how to approach this question.
Thank you.

Hints:


1) To find the perimeter, you need to find the lengths of the 3 sides. To find the length of any side, you find the distance between the two points. Use the distance formula for that.


2) To find the area of any triangle with 3 sides given, you use Heron's Formula
