A plot 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?

88 ft

Step-by-step explanation:

Given,

The measurement of the garden = 16-ft-by-20-ft,

That is, length of garden = 16 ft,

Width of garden = 20 ft,

If plot is obtained after surrounding the garden by 2 ft wide wall,

So, length of plot = 16 + 4 = 20 ft,

Width of plot = 20 + 4 = 24 ft,

So, the perimeter of the entire plot = 2 (length + width)

= 2 (20 + 24)

= 88 ft

jeez no one answered, i know someone has the answers.
