Area of Plot+Sidewalk:

A = LW

A = (30+2*3)*(20+2*3)

A = 936

------------------------------------

Area of Plot only

A = LW

A = 30*20

A = 600

------------------------------------

Area of Sidewalk only = (Area of Plot+Sidewalk) - (Area of Plot only)


Area of Sidewalk only = 936-600


Area of Sidewalk only = 336


So the area of the sidewalk is 336 square feet
