I know square feet need to find length and width

Question

I have 138.13 sq ft

what’s my length and width

Answer 1

If the figure is a rectangle, the only thing you can know here is the product of length (L) and width (W).

LW = 138.13 square feet

Without more information, such as the perimeter, or a relation between width and length (other than area), you cannot completely answer the question.

However, if the figure is a square, then the length and width are the same, and they are equal to the square root of the area. But the question does not say if the figure is a rectangle, a square, or maybe even something else.
