The description is not clear. Is the path inside the garden or outside the garden? Once you know which kind, you can use either or both of these video presentations for help:

outside border of uniform width, rectangle

inside border of uniform width, rectangle

Write an equation: x if the width of a uniform path of garden that is 8 m wide and 10 m long. The area of the path is 40 m^2.
------------------------------------------------------------

I will assume that the path around the garden is outside the garden.
(It was not clearly pronounced in the condition although.)

Then the equation is

(L+2x)*(W+2x) - LW = 40.

Here L is the length of the garden and W is the garden width.
L and W are given.
