it is forming a right angle triangle which means it on angle will be 90
OpenStudy (anonymous):
It's a square so both sides will be the same.
\[a^2+a^2=44^2\]\[a^2+a^2=1936\]\[2a^2=1936\]\[a^2=968\]\[a=\sqrt{968}\]\[a=31.11\]\[4a=124.44\]

36 <-- answer
OpenStudy (anonymous):
The question is asking for the perimeter of the picture, correct?

yeah
OpenStudy (anonymous):
And 36 can not be the perimeter.
OpenStudy (cookie_2046):
i mean no
OpenStudy (anonymous):
Well when I think of framing something, I think of surrounding all sides (or the perimeter) with frame. What else could it be referring to?
OpenStudy (cookie_2046):
well i'm running out of time can you give me the answer :)

I already did, along with my explanation :). In my explanation, the "a" represents the side of the square.

Remember to round the answer, so 124.
