## christinestutes one year ago Find the area of the triangle with vertices at the given points. (0, 0), (0, 3), (4, 0) a. 3 units2 c. 6 units2 b. 7 units2 d. 9 units2

1. christinestutes

Not sure how to figure this out given vertices

2. christinestutes

3. Nnesha

first you have to find distance of given points

4. Nnesha

$\huge\rm A=\frac{ 1 }{ 2 }bh$ formula to find area of triangle

5. christinestutes

I know formula but don't know how to find distance of given points

6. Nnesha

http://prntscr.com/7g5c3h here draw points on the graph you can draw triangle now you need h and b so find distance between (0,0)(0,3) AND (0,0)(4,0)

7. Nnesha

formula to find distance is $\huge\rm \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}$

8. Nnesha

you DON'T have to use that formula just look at the graph and count how many unit its increasing vertical and horizontal

9. christinestutes

Is the answer 6 units squared

Ok Thanks for the graph. I get it now. Wasn't sure what to do with vertices. I have an online class but have never had Geometry yet.

12. christinestutes

I appreciate the help and explanations.

13. Nnesha

np :-) gO_Od luck!

14. Nnesha

thanks :-)
