Question

The three vertices of triangle ABC are A(1,4) B(-2,2) and C(3,2). Plot these point on graph paper and calculate the area of triangle ABC​

Answer 1

Answer:

ABC is an isosceles triangle and lengths of sides AB=BC=

29

units

Now, area of the triangle =

×4×5=20squnits (Since, base is distance between A and C and height is the distance between B and the base AC

Answer 2

Step-by-step explanation:

The vertices of a triangle are A(1,4), B(-2,2), C(3,2). Therefore, the area of triangle ABC is 5 square units.
