Find the area of a cement walk 3 feet wide that surrounds a rectangular plot of ground 86 feet long and 42 feet wide?
--------------------------------------------
Draw the picture as a rectangle inside a rectangle.
Area of inner rectangle: 86*42 = 3612 sq. ft.
------------------------
Area of outer rectangle: (86+6)(42+6) = 4416 sq. ft.
--------------------------
Area of cement walk = outer area - inner area = 804 sq.ft.
