Question

find the area of triangle joining the mid points of the sides of triangle whose vertices are (3,2) (-5,-6) and (7,4)

Answer 1

we know that.,
are of triangle
=1/2 (x1(y2 - y1) +x2(y1-y3) +x3(y3-y1)
= 1/2(3(-6-2)+(-5)(2-4)+7(4-2)
=1/2 (3(-8)+10 + 14
= 1/2 (-24 + 10 + 14)
= 1/2 ( -24 + 24 )
=1/2 and
