Answer:
hello : 
the area is : A= w ×l     ...   w :  the width    l : the length 
A = 323     l = 19     w ?
l = A/w
l = 323/ 19
 l = 17 feet

Prime numbers are those that cannot be divided by another number (other than themselves and 1). In other words, prime numbers have factors of themselves and 1.
For example, 3 is a prime number because its only factors are 3 and 1.
6 is not a prime number because it can be factored to 3*2.
Therefore, the correct answer is c. 3,11,23,31
