What’s the correct answer for this question?

Answer

C. 14

Explanation

The area of triangle = 1/2(base)(height)

The height:

the height is the distance from point (2,-3) perpendicular to the base intersecting it at point (2,1)

the height is then the distance between the 2 points = 4

The base:

the base is the distance between points (7,1)and (0,1) = 7

The area:

the area = 1/2 x 4 x 7 = 28/2 = 14 units²
