Answer:

(b) 1.7 in

Explanation:

The area of a regular polygon in terms of perimeter and apothem is given by the formula ...

A = 1/2Pa

For a hexagon, the perimeter is 6 times the side length, so this becomes ...

A = 1/2(6s)a = 3sa . . . . . for side length 's' and apothem 'a'

__

Solving for the apothem, we find ...

a = A/(3s)

For the given values of area and side length the apothem is ...

a = 10.4/(3·2) = 1.733... ≈ 1.7 . . . inches

The apothem, rounded to tenths, is 1.7 inches.
