That 44 inches is the diagonal / hypotenuse of a square / right triangle.  Use Pythagorean Theorem to determine the length of one side of the square.

mahoganie.carson · Answer

use the pythagoras theorem
since all the sides of a square are equal
x^2 +  x^2 = 44^2
where x is the length of one side of the picture

directrix · Answer

Or, use the 45-45-90 theorem and divide the diagonal length by √2 to get the length of one side of the frame.

Agreed.  So, Blu_Seaa, what is the length of one side of this square?

Now, approx. how much molding would be needed to construct a picture frame from this material that will have a 44 inch diagonal?

blu_seaa · Answer

I'm not really sure, to be honest...

mahoganie.carson · Answer

the total length of frame need will be 4 times x
