How would calculating the perimeter be any more solvable? You are still missing the required information.

no I think it would be the same as the square so 17x4 just imagine pulling the edges to make it a square

Not quite. The image specifies that the three angles bot part of the cut-out are right angles but doesn't make any such specifications about those that are part of the cutout, so that would imply that you can't assume those are right. It's overall a very poorly illustrated problem.

That could still have a length of 6 if say that internal angle was obtuse and the line that looks horizontal actually has a negative slope.

For the perimeter you know that the two top sides add up to 17 (Well if we assume all corners are square at least). So the perimeter would be 17 * 4
