The area is 166.3 square inches.
It is 679 square metres.
There is no need to round 1097 to any decimal places as there are no digits following a decimal point.
85 rounded to three decimal places is 85.000
round 0.2975 to 1 decimal place = 0.3
to round 68.4 to one decimal place = 68.4
s = 8 and a = 1.3 are not compatible for a regular hexagon.

The answer depends on what the lengths s and a are meant to represent.
It's regular, it has 6 sides and each side is 8.2 inches. Wrap a wet towel round your head and I'm sure you'll be able to work it out.
The question was extremely poorly worded since it gave no information on what S and a were. However, having figured that out, the answer is 166.3 square units.

Find the area of an equilateral triangle that has a perimeter of 21 inches. Round the answer to one decimal place.
A hexagon can be drawn either with a compass or round object, or free hand. A hexagon has six equal sides and six equal angles. For a perfect hexagon, a compass is recommended. * * * * * While a hexagon does have six sides and six vertices, these need not be equal. If the sides are all equal AND the angles are equal, then the hexagon is a regular hexagon.
The exterior angles of any polygon add up to 360° (imagine walking round any polygon - you will have made a complete turn). There are six external angles in a hexagon. If it is a regular hexagon, each external angle will be 360°/6 = 60°.
