How do i find the area of a triangle? For example:

Question

A squared + b squared= c squared
8.5 squared + 6.4 squared= c squared
72.25 + 40.96= c squared
113.21=c squared
10.6400188=c

even tho i thought this was the answer it is not because it does not solve the code on the worksheet. does anyone have any idea what i did wrong and how to get the right answer?

Answer 1

area of triangle = 1/2*height*base.
I think you have the area confused with the Pythagorean theorem.
