No. A diagonal goes from corner to opposite corner, which will always be a longer distance than the side length. You can use Pythagoras' theorem to work out the length of the diagonals. It will be the square root of (a2+b2) where a and b are the long and short side lengths of the rectangle respectively. The result will clearly be greater than either a or b.
Parallelogram and a rectangle
The answer will depend on what aspect you wish to sum: its side lengths, it interior/exterior angles, its diagonals.
You need more information: the length of a side. Then, since the diagonals bisect one another at right angles, you can use Pythagoras's theorem to calculate their lengths.
Lengths of: equal side+equal side+base = perimeter
9 is shortest integer side length greater than 17/2
No. Even in the non-US use of the term (a quadrilateral with at least one set of parallel lines), the lengths of the parallel lines may not be the same, and/or the angles formed by each adjacent side may be different (as in a rhomboid), resulting in diagonals of extremely different lengths.Only in rectangles are diagonals "always" of equal length.

See if the diagonal measurements are equal, and see if the side lengths are equal. If both are true, it's a square. If only the diagonals are equal, it's a rectangle. If the diagonals are not equal, it's a non-orthogonal parallelogram.
Yes, those polygons which have angles of 90 degrees and equal side lengths are called squares; those with uneven side lengths are called rectangles.
rectangles have 2 sets of parellel sides but 2 different pairs of side lengths
Parallelogram and a rectangle
No, for a polygon to be regular it must have equal side lengths and angles.
The diagonals of rectangles are rotational lines of symmetry but not reflective. To be reflective lines, folding along the line has to give the same shape on each side.
A rhombus or a square. In rectangles (unequal side length) this does not occur.
The diagonals of a rhombus bisect one another at right angles. So you can use Pythagoras on half the lengths of the diagonals. If the two diagonals ore of lengths a and b, then side2 = (a/2)2 + (b/2)2 or, equivalently, side = 1/2*sqrt(a2 + b2)
The area of an octagon with corresponding side lengths equal to 218 is about 229,466.2 units2
Yes, because the side a and side c are always equal in length and side b and side d are always equal in length.
