Find the area of a cement walk 2.5 feet wide that surrounds a rectangular plot of ground 68 feet long and 34 feet wide.
~~~~~~~~~~~~~~~~~~~~~~~~
The smaller rectangle (ground plot) has dimensions 68 ft and 34 ft.
Its area is 68*34 square feet.
The larger rectangle has dimensions 68 + 2*2.5 = 73 ft and 34 + 2*2.5 = 39 ft.
Its area is 73*39 square feet.
The area of the cement walk is the difference 73*39 - 66*34 square feet.
