Are there any dimensions on the triangle? or is it in terms of s? if so the answer would be 2s/sqrt(3) or you can rationalize the bottom and youd get 2sqrt(3)s/3
The picture's length and width are 18 and 5. You subtract 2 instead of 1 because you are subtracting 1 on both sides of the frame.
The area of the picture is 90, and the area of the whole thing, picture and picture frame, is 20*7=140.
So, to find the area of just the picture frame, you subtract 90 from 140 to get 50in^2, which is your last answer choice.
The answer is 6.345 is rounded up to 6.

Answer: Yes, those sides form a right triangle</h3>
===================================================
Work Shown:
a^2+b^2 = c^2
15^2+20^2 = 25^2
225+400 = 625
625 = 625
Since the last equation is true, this makes the first equation true for those a,b,c values. Therefore, by the pythagorean theorem converse, this is a right triangle.
Side note: c is always the longest side.
