11. Find the area of the regular polygon.

Answer:
105 mm²
Step-by-step explanation:
The area (A) of the regular polygon is calculated as
A = [tex]\frac{1}{2}[/tex] pa ( p is the perimeter and a the apothem )
Here a = 5 and p = 6 × 7 = 42, thus
A = [tex]\frac{1}{2} }[/tex] × 42 × 5 = 21 × 5 = 105 mm²
