In the rectangular coordinate system, what is the area of triangle CDE with points
C=(7,2)
D=(3,9)
E=(1,4) Choose the correct choice from the following choices:
A) 17
B) 16.3
C) 18
D) 19
E) 15
Use the formula of the distance formula   square root (x2-x1)^2+(y2-y1)^2   Do this for each of the sides and then the value is given as 17.
