Question

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

Answer 1

Not sure how to figure this out given vertices

Answer 2

help PLEASE

Answer 3

first you have to find distance of given points

Answer 4

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

Answer 5

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

Answer 6

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)

Answer 7

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

Answer 8

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

Answer 9

Is the answer 6 units squared

Answer 10

:-)

Answer 11

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.

Answer 12

I appreciate the help and explanations.

Answer 13

np :-) gO_Od luck!

Answer 14

thanks :-)
