what is the area of the triangle (2,7) (6,4) (2,-2)

Answer 1

(2,7), (6,4), and (2,-2) are vertices of a triangle.

plot the points, connect them with straight line segments

the vertical side on the left is length of 7--2 = 9.

use 9 as the base

b=9

the height is then 6-2 =4

h=4

Area =half of base times height = bh/2 = (9)(4)/2 = 18

rotate the triangle 90 degrees counterclockwise, then 9=b, 4=h
