A rectangular number is the product of two consecutive integers, that is, n (n + 1).
A composite number is a positive integer with more than two factors.
Rectangular numbers are a subset of composite numbers. The squares of prime numbers will be composite but not rectangular.

Both. It is a number and it is composite.
Composite number
not necessarily
A rectangular umber is essentially a composite or non-prime number. If a number n is composite then it can be factorised as p*q. In that case, it can be represented as an array of p rows and q columns in a RECTANGULAR array.
Rectangular numbers are a subset of composite numbers. The squares of prime numbers will be composite but not rectangular.
The Number of factors, (That is the number of pairs, such as 2= 1x2, 2x1), is equal to the number of rectangular arrays which can be made for each composite number. As such, the number of factors in the number 9 is 3, (1,3,9), and the number of rectangular arrays is also three (1x9, 9x1,3x3). Hope this helps!
There is no such formula. Rectangular numbers are composite numbers and there is no known formula that will generate either composite numbers or prime numbers.

515 is a composite number. NB Remember #1 ; Any number ending in an even number ( 0,2,4,6,8) is composite. #2 ; Any number ending in '0' or '5' is composite. #3 ; Any number whose digits sum to '9' is composite. e.g. 135 = 1 + 3 + 5 = 9 is a multiple of '9'. #4 ; You only need to divide by '3' or '7' to test for prime number. It the result is a whole number then it is NOT a prime. NNB Since the above number , 515, ands in ;5; then it is composite.
