Because that's one of the specifications in the definition of a rectangle. If it doesn't have
exactly four sides, then it doesn't satisfy the definition, and we don't call it a rectangle.
Your question is like asking: Why is a long-haired person a woman ?
I had to clean that up a lot, but I hope there's enough of it left to demonstrate my point.
Rectangles must always have 4 sides. As there are two rectangles, there must be 8 sides. However, if these two rectangles have identical sized sides and they are placed against each other so that they look like one rectangle, there will only be 4 sides.
Well, squares do have equal sides but rectangles have two pairs of equal sides
A rectangle is a quadrilateral that has four sides.
squares rectangles.
Providing they are not contiguous there are 16
Do 4 sides times 4 rectangles. So it would be 4x4=16 sides
All rectangles are quadrilaterals. A quadrilateral has 4 sides; all rectangles have 4 sides; thus all rectangles are quadrilaterals.

yes if it is a square. squares are rectangles with their 4 sides and 4 right angles, but rectangles are not squares without 4 equal sides

Yes, all rectangles are quadrilaterals because they have four sides and all quadrilaterals have four sides.
Hexagons have 6 sides and rectangles have 4 sides
squares and rectangles.
trapezoids and rectangles, are both quadrilateral (which means shapes with 4 sides). rectangles and trapezoids are also polygons.
