A rectangle garden has a walk around it with x+2 width. The garden is 35 ft. by 25 ft.

Answer provided by our tutors
The dimensions of the garden together with the walk around are:
(35 + x + 2) by (25 + x + 2)
that is
(x + 37) by (x + 27)
The combined area is:
A = (x + 37)(x + 27)
A = x^2 + 64x + 999
