In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
regular hexagon:
apothem = 10.4 yd
side = 12 yd
Step 02:
geometry:
area:
area of hexagon = 1/2 * apothem * perimeter
perimeter = 6 * side = 6 (12 yd) = 72 yd
area of hexagon = 1/2 (10.4 yd) (72 yd) = 374.4 yd²
The answer is:
374.4 yd²
