Question

In a rectangular coordinate system, what is the area of a triangle whose vertices have the coordinates (4,0), (6,3) and (6,-3)?
forget the formula please help...!!

Answer 1

draw the points...u'll get the answer

Answer 2

i mean on xy plane

Answer 3

manitude =\[\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}\]
draw the rectangle .. find the magnitude of two sides.. apply the formula or rectangle.

Answer 4

so area= 1/2*6* 2

Answer 5

i want to know that formula
1/2(x1(y2-y1)+x2(y3-y2)+x3(y2-y1))
is that correct?

Answer 6

these all take time

Answer 7

formula is 1/2 { x1(y2-y3) + x2(y3-y1) + x3(y1-y2)}

Answer 8

ok
