5-50.

Calculate the area of the right triangle that has vertices at *A*(525, 260), *B*(725, 260), and* C*(525, –10). Homework Help ✎

The area of a triangle can be calculated as (0.5)(base · height)

where the base and height must be perpendicular to each other.

Consider graphing the three points and see if you can spot the two sides that are perpendicular.
