Question

find the area of triangle ABC the coordinates of vertices are 1, 2 and 6, 2 and 5, 3 ​

Answer 1

Hello! A very good evening

Here is your correct and wanted answer...

A =( 1,2)

B =(6,2)

C =(5,3)

Ar. Of triangle = 1/2 ( x1 ( y2-y3) + x2(y3-y1) + x3(y1-y2)

Ar.of triangle = 1/2 ( 1 (2-3) + 6 (3-2) + 5(2-2)

Ar.of triangle =1/2(-1+6+5)

Ar.of triangle= 1/2(10)

Ar.of triangle= 5 sq units.
