In a rectangular coordinate system, what is the area of a triangle whose vertices have the coordinates (4, 0), (6, 3), and (6, -3)? Choose the correct choice from the following:	A) 7.5	B) 7	C) 6.5	D) 6	E) 5.5
Area of the triangle = 1/2*base*height.   Here base = Distance between (6,3) and (6,-3) =&gt; 3-(-3)=
