The area of triangle whose vertices are at ( -3,1) , (4,3) , (0,7) is

1 thought on “The area of triangle whose vertices are at ( -3,1) , (4,3) , (0,7) is”

1. Step-by-step explanation:

   Using Formula,

   [tex]\sf{\boxed{\sf{ar(∆)= x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y2)}}}[/tex]

   [tex]\sf{\implies{ar(∆)=(-3)(3-7)+4(7-1)+0(1-3)}}[/tex]

   [tex]\sf{\implies{ar(∆)=(-3)(-4)+4(6)+0}}[/tex]

   [tex]\sf{\implies{ar(∆)=12+24}}[/tex]

   [tex]\sf{\implies{\boxed{\sf{ar(∆)=36 \:squareunit}}}}[/tex]

   Hope it helps…❣️❣️❣️
