The perimeter of the square is 16/19x - 36 units, where x is the given side length correct option is b.

Identify the given information

The problem states that a square has a side length of 4/19x - 9 units. We are asked to find the perimeter of the square in terms of x.

Recall the formula for the perimeter of a squareThe perimeter of a square is the total length of all its sides added together. Since all sides of a square are equal, we can simply multiply the side length by 4 to find the perimeter.

Therefore, the formula for the perimeter of a square is:

P = 4s

where P is the perimeter and s is the side length.

Substitute the given side length into the formula

In this case, the side length of the square is given by 4/19x - 9 units. Substituting this into the formula, we get:

P = 4(4/19x - 9)

Expand the parentheses and simplify

Expanding the parentheses, we get:

P = 16/19x - 36

Write the answer in terms of x

The perimeter of the square in terms of x is 16/19x - 36.

Therefore, the correct answer is B. 16/19x - 36.
