Answer questions about the following

What is the value returned by triangleArea(3,4,5)? *

Which of the following variables and code might you expect to see in some implementation of triangleArea? (select all that are reasonable to see) *

semi = (a + b + c)/2

y = (semi - b)

area = 0.5 * base * height

ret = math.sqrt(semi*x*y*z)

if semi == 0:

if semi - b < 0:

Required

Which of the following are likely true?

It can be useful to include print statements in the function triangleArea during the debugging process

using the float conversion function, as in float(2) or float("12.0") will be seen in nearly all implementations of triangleArea

It's an error to take the square root of a negative number, but negative numbers aren't a concern with triangleArea

There is a built-in Python function triangleArea, so writing one isn't required

You should spend a lot of time thinking about this problem if it was on exam 1
