A triangle in the xy-coordinate plane is formed by the points (−2,0), (4,0), and (1,5). What is the area of this triangle?
5 square units
9 square units
10 square units
15 square units
The formula of area of triangle is (BxH)/2. By folowing the coordinates given and the formula, our B=6, H=5. So... (BxH)/2 which is (6x5)/2 which is 30/2= 15 sqr. units.
