Explanation:

Step1: Convert fractions to sixteenths

$\frac{1}{8}=\frac{2}{16}$, $1\frac{1}{16}=\frac{17}{16}$, $\frac{3}{16}$ remains.

Step2: Sum all sides

Perimeter = $\frac{3}{16} + \frac{2}{16} + \frac{17}{16} + \frac{2}{16}$ = $\frac{3 + 2 + 17 + 2}{16}$ = $\frac{24}{16}$ = $\frac{3}{2}$? Wait, no, wait: Wait, the trapezoid has four sides: top base $\frac{3}{16}$, two legs $\frac{1}{8}$ each, and bottom base $1\frac{1}{16}$. Wait, recalculating: $\frac{3}{16} + \frac{1}{8} + 1\frac{1}{16} + \frac{1}{8}$. Convert $\frac{1}{8}$ to $\frac{2}{16}$, so: $\frac{3}{16} + \frac{2}{16} + \frac{17}{16} + \frac{2}{16}$ = $\frac{3 + 2 + 17 + 2}{16}$ = $\frac{24}{16}$ = $\frac{3}{2}$? No, that's 1.5, but wait, maybe I messed up the bottom base. Wait, $1\frac{1}{16}$ is $\frac{17}{16}$, yes. Wait, no, wait: $\frac{3}{16} + \frac{2}{16} = \frac{5}{16}$; $\frac{17}{16} + \frac{2}{16} = \frac{19}{16}$; then total is $\frac{5}{16} + \frac{19}{16} = \frac{24}{16} = \frac{3}{2}$? But that's 1.5, but maybe I made a mistake. Wait, no, wait: Wait, the problem is a trapezoid, so four sides: top: 3/16, left leg: 1/8, bottom: 1 1/16, right leg: 1/8. So adding them: 3/16 + 1/8 + 1 1/16 + 1/8. Let's convert all to sixteenths: 3/16 + 2/16 + 17/16 + 2/16 = (3 + 2 + 17 + 2)/16 = 24/16 = 3/2 = 1.5? But that seems low. Wait, maybe the bottom base is 1 1/16? Wait, 1 1/16 is 17/16, yes. Wait, maybe the original problem has a typo? Or maybe I miscalculated. Wait, no, let's do it again: 3/16 + 1/8 is 3/16 + 2/16 = 5/16. Then 1 1/16 + 1/8 is 17/16 + 2/16 = 19/16. Then 5/16 + 19/16 = 24/16 = 3/2 = 1.5. But the answer is supposed to be 2? Wait, maybe I misread the bottom base. Wait, maybe the bottom base is 1 1/16? Wait, no, maybe the bottom base is 1 1/16, but let's check again. Wait, 3/16 + 1/8 + 1 1/16 + 1/8. Let's convert 1 1/16 to improper fraction: 17/16. Then 3/16 + 2/16 (for first 1/8) + 17/16 + 2/16 (for second 1/8) = (3 + 2 + 17 + 2)/16 = 24/16 = 3/2 = 1.5. But the user might have made a mistake, or maybe I misread the diagram. Wait, maybe the bottom base is 1 1/16, but maybe the legs are 1/8, top is 3/16. Wait, maybe the correct calculation is: 3/16 + 1/8 + 1 1/16 + 1/8 = 3/16 + 2/16 + 17/16 + 2/16 = 24/16 = 3/2. But the initial thought of 2 was wrong. Wait, no, maybe the bottom base is 1 1/16, but let's check the arithmetic again. 3 + 2 + 17 + 2 = 24. 24 divided by 16 is 1.5, which is 3/2. So the perimeter is 3/2 miles, or 1 1/2 miles. But maybe the diagram was misread. Wait, maybe the bottom base is 1 1/16, but perhaps the top base is 3/16, legs 1/8, and bottom base 1 1/16. So the calculation is correct. So the perimeter is 3/2, which is 1.5. But the user's expected answer might be 2? Wait, maybe I made a mistake in the bottom base. Wait, 1 1/16 is 1 + 1/16, so 17/16. Then 3/16 + 1/8 + 17/16 + 1/8. Let's add the whole numbers and fractions separately. The whole number part is 1. The fraction parts: 3/16 + 1/8 + 1/16 + 1/8 = (3/16 + 1/16) + (1/8 + 1/8) = 4/16 + 2/8 = 1/4 + 1/4 = 1/2. So total perimeter is 1 + 1/2 = 3/2. So the answer is 3/2, or 1 1/2.
