Question

find the area of triangle by joining the points (2,3),(6,3),(4,7)​

Answer 1

Step-by-step explanation:

area of triangle = 1/2|x1(y2-y3)+x2(y3-y1)+x3(y1-y2)|

where (x1,y1) (x2,y2) (x3,y3)

are the points joined to form triangle

substitute and get the answer

Answer 2

Answer:

Namaskaram......

Area of triangle =1/2 | x1(y2-y3) +x2 (y3-y1) +x3(y1-y2) |

here x1= 2,x2 = 6 ,x3 =4

y1= 3,y2= 3 ,y3 = 7....

∆ = 1/2 | 2(3-7)+6(7-3)+4(3-3) |

= 1/2 | 2(-4) +6(4)+4(0)|

= 1/2 | -8 +24+0 |

= 1/2 | 16 |

= 8 sq.units...
