No single integer satisfies both requests. 80 is the only integer with exactly 5 factor pairs in that range, but it has two prime factors. 64 and 81 have one prime factor but 4 and 3 factor pairs respectively.
rectangles
It is a triagular prism
They have two pairs of sides that are parallel. Trapeziums have exactly one pair of sides that are parallel.
A parallelogram does not have to be a rectangle, but since a parallelogram but have 2 sets of parallel sides, it often is. However, rectangles are always parallelograms. I hope this helps, didint exactly understand the question.
Algeria, Angola, Burkina, Haiti, Indonesia, Liechtenstein, Malta, Monaco, Poland, San Marino, Singapore and Ukraine have flags with exactly two rectangles which are congruent. There are also many flags with more than two rectangles.
rectangles
5 rectangles means 5 prime numbers in this number 64 = 25 = 64 x 1 = 32 x 2 = 16 x 4 = 8 x 8 : 4 rectangles 96 =24 x 3 = 32 x 3 = 16 x 6 = 8 x 12 = 4 x 24 = 2 x 48 = 1 x 96 : 6 rectangles 72 = 23 x 32 = 72 x1 = 36 x 2 = 18 x 4 = 9 x 8 = 3 x 24 : 5 rectangles!
80
It is a triagular prism
It's very easy for two rectangles to have the same area and different perimeters,or the same perimeter and different areas. In either case, it would be obvious toyou when you see them that there's something different about them, and theywould not fit one on top of the other.But if two rectangles have the same area and the same perimeter, then to look at themyou'd swear that they're the same rectangle, and one could be laid down on the otherand fit exactly.
