The vertices of a triangle have coordinates (1,1), (7,1) and (5, 3). What is the area of this triangle?

Uhh. Base is 6. Height is 2.

 

Split it into 2 triangles.

 

First one, base is 4, height is, as you know, 2.

 

First triangle is 4, been there, done that.

 

Second triangle has base of 2. Don't need to multiply by height. Second triangle is 2.

 

Add them... 4+2=6
