A rectangle has a perimeter of 16 inces. it's width is one-third of it's length. Find it's length.
I just need the set up, thank you!!

To find the length of the rectangle, we can use the information given in the question. Here's how we can set up the problem:
Let's assume the length of the rectangle is represented by 'L' inches.
According to the question, the width of the rectangle is one-third of the length. So, the width can be represented as '1/3L' inches.
The perimeter of a rectangle is given by the formula:
perimeter = 2 * (length + width)
Substituting the given lengths into the formula, we get:
16 = 2 * (L + 1/3L)
Now, we can solve this equation to find the value of L.
