Question

Three points (1,5), (2, 4) and (3, 3) are
(a) Vertices of a triangle of area 6 sq.unit
(b) Vertices of a triangle of area 4 sq.unit
(c) Collinear points
(d) None of these​

Answer 1

Step-by-step explanation:

The legs of the three triangles can be found by simple subtraction of coordinates and then used to find the area since the area of a triangle is one-half the base times the height. Area of triangle A = 3 ( 3 ) / 2 = 9/2.
