Question
Find the area of the triangle with the vertices given. Assume units are in cm.$$(2,1),(3,7), \text { and }(5,3)$$
Step 1
The formula is: \[Area = \frac{1}{2} |x_1(y_2 - y_3) + x_2(y_3 - y_1) + x_3(y_1 - y_2)|\] where \((x_1, y_1), (x_2, y_2), (x_3, y_3)\) are the coordinates of the vertices of the triangle. Show more…
