question_answer 1)

Using integration, find the area bunded by the triangle whose vertices are (–1, 0), (1, 3), are (3, 2). 

Answer:

Let vertices of the triangle area       A = (?1, 0), B = (1 3), C = (3, 2)                    Equation of AB                         Equation of BC                                             Equation of AC                   Area                                           = 3 + 5 ? 4 = 4.
