It's a factor. This concept is widely used throughout algebra, and you'll probably bump into it through the end of high school and beyond.
A common use is expressing a term in <em>prime factorization</em>, or reducing a number to its most base parts- primes. For example:

Of course, a number like 13 which is already prime is made up of itself and 1. <em>Factors do not have to be primes.</em> 20 is also reducible through combinations of 1, 2, 4, 5, 10, and 20. Prime factorization is just a handy example.
Basically, factors multiply with each other to create other numbers, and numbers can be reduced down to their factors.

I (interest) = $ 150.00
Answer:
The length of the brown shelf is 11ft
Step-by-step explanation:
In this question, we are asked to calculate the length of a brown shelf, given that the length of the orange shelf is a particular length.
Now as we are told from the question, the length of the brown shelf is twice that of the yellow shelf. What we simply need to do is to multiply the length of the orange shelf by 2 to get the length of the brown shelf.
The length of the orange shelf is 5ft 6 inches, multiplying this by 2 will yield a length of 10ft 12 inches
Now, since 1ft = 12 inches, this means the length of the brown shelf would be 11ft in total
