I got #1600"ft"^2#

Consider the diagram:

here we can see two rectangles:

the small one of dimensions #100"ft"# and #50"ft"#

the big one of dimensions #[100+(2*5)]"ft"# and #[50+(2*5)]"ft"# formed considering also the walk.

Subtracting the area of the small one from the area of the big one we should get the area of the walk.

#A=[100+(2*5)xx50+(2*5)]-[100xx50]=6600-5000=1600"ft"^2#
