Answer:
16√2 ≈ 22.63
Step-by-step explanation:
A graph is informative. It shows us the sides of the polygon have slopes of ±1, so the perimeter can be figured in units of the diagonal of a unit square. (The length of that diagonal is √2.) The short sides are 3 such units long, and the long sides are 5 such units. Then the total perimeter is ...
P = 2(3 +5)√2
P = 16√2 ≈ 22.63
