Question

The area of triangle formed by point P(0,0),Q(3,0)and R(0,6)is *

​

Answer 1

"

If

(x1, y1), (x2, y2), (x3, y3) (x1, y1) (x2, y2), (x3, y3)

are the vertices of a triangle then its area is given by

Area = [1/2 (x1(y2 −y3)+x2 (y3 −y1 )+x3 (y1 −y2 ))]

Area = 1 2 [(0(5-4)+0(4-1)+3(1-5)] ⇒ [ 1 2 (−12)] ⇒ 6 sq.

Answer 2

Answer:

the area of triangle will be 9.
