Answer:
12√2 ≈ 16.97
Step-by-step explanation:
Points A and B are on grid lines. The difference B-A is (2, 2), so the distance formula will tell you the length of that segment is ...
√(2²+2²) = 2√2
The regular hexagon has 6 sides all the same length. The perimeter is the sum of those lengths, so is ...
6 × 2√2 = 12√2 ≈ 16.97 . . . . units
