Answer:
532.4 in²
Step-by-step explanation:
The area (A) of the regular pentagon is calculated as
A = 0.5 × perimeter × apothem
Perimeter = 5 × 17.6 = 88 in
The apothem is the segment from the centre to the midpoint of one of the sides.
Here the apothem = 12.1 in, thus
A = 0.5 × 88 × 12.1 = 44 × 12.1 = 532.4 in²
