1. Find the area of the triangle formed by the vertices (4,5), (10,12) and(-3,2).

SOLUTION :

GIVEN POINTS :

• The vertices of the given triangle are ( 4 , 5 ) , ( 10, 12 ) and ( - 3 , 2 ) .

Area :>

( 1 / 2 ) × | 4 × 12 + 10 × 2 + 3 × 5 - { 5 × 10 + 12 × -3 + 2 × 4 } |

=> ( 1 /2 ) × | 83 - 22 |

=> 61 / 2 unit ^2
