Question

Find the area of triangle formed by joining midpoints of the sides of the triangle whose verticals are A(2,3), B(4,4)and C(2,6).

Answer 1

Answer:

Area =

(1/2)|x1(y2-y3) +x2(y3-y1) +x3(y1-y2)|

=(1/2)|2(4-6)+4(6-3)+2(3-4)|

=(1/2)|2(-2)+4(3) + 2(-1)|

=(1/2)|-4 +12 -2|

=(1/2)|6|

=6/2

= 3

Therefore, Area = 3 square units.
