Answer: 21 . . . . . .
Credit to the person below-
that would be 48/9 because it would be kittens(48) to puppies(9) then simplified to 16/3.
Step-by-step explanation:
the outer left side is also 50 ft.
in inner (upper) left side is also 13 ft.
the bottom line is 10+20+11 = 41 ft
this is all possible because all the angles are clearly right angles (90°).
so, the perimeter is
2×(10+20+11) + 2×50 + 2×13 = 82 + 100 + 26 = 208 ft
