Aplot of land contains a 16-ft-by-20-ft garden, which is surrounded by a 2-ft wide wall on all sides. what is the
perimeter of the entire plot of land?
64 ft
72 ft
80 ft
88 ft

The 2-ft wide wall on each side adds a total of 4-ft to the each size of the land dimensions making it 20-ft-by-24-ft land now.
Perimeter is calculated as an addition of all sides so 20+20+24+24 = 88-ft perimeter assuming it is a rectangle land shape.
