Question

What is the area of this triangle?

Answer 1

To find the area of a triangle, you must fin the base (b X l ) and then divide it by 2, and add that height.

Answer 2

Area of triangle is 1/2 times base times height
lets say the base is from x1,y2 to x1,y1 the distance is 6 units

1/2 times 6 times height
from x1,y1 to x3,y3 is 7 units to the right
1/2 times 6 times 7=3 itmes 7=21

area=21 square units or
21 units^2
