Question

Using integration find the area of region bounded by the triangle whose vertices are (-1, 0), (1, 3) and (3, 2).

Answer 1

We need line eq: for line AB, BC and AC

so line AB,

Required area is shaded area 

⇒[Area under line AB from x = -1 to x = 1 + Area under BC from x = 1 to x = 3 - Area under AC from x = -1 to x = 3]
