What is the area in square units of triangle POR2

Answer 1

Answer:7

Explanation:

Triangle fits inside of a rectangle (A=15).

If the rectangle is drawn around the triangle, three other right triangles are formed outside of it. Find the area of each right triangle (4, 1.5, and 2.5), add those together, and subtract from the area of the rectangle.

(15 - 8 = 7)
