The length was originally 6 feet while the new area is 36 feet^2.
Area of a square
A square it is quadrilateral hence it has four sides. We have the new area of the square garden as 25 and given by (x - 1)^2 = 25.
Hence;
(x - 1)^2 = 25
(x - 1) = √25
(x - 1) = 5
x = 5 + 1 = 6 feet
So, the new area of the garden = 6^2 = 36 feet^2
