Question

The area of the triangle formed by the points (0,0),(4,0) and (0,6) is

Answer 1

( x1 , y1 ) = ( 0, 0 )

( x2 , y2 ) = ( 4, 0 )

( x3 , y3 ) = ( 0, 6 )

Area of the triangle when all three vertices are given is given by :

A = x1 ( y2-y3 ) + x2 ( y3-y1 ) + x3 ( y1 - y2 )

A = 0 ( 0 - 6 ) + 4 ( 6 - 0 ) + 0 ( 0 - 0 )

A = 4 x 6

A = 24 sq units
