Question

Calculate the area of triangle WXY with altitude YZ, given W (2, −1), X (6, 3), Y (7, 0), and Z (5, 2).

8 square units

9.4 square units

7.7 square units

12 square units

Answer 1

You need to calculate the distance between the points W and X as well as the points Y and Z.

Then use the formula \[A=\frac{1}{2}bh\]
where b = the distance between W and X,
h= the distance between Y and Z.
