Answer:

A = 832 m²

Step-by-step explanation:

using the formula of a regular polygon with,

n = number of sides

s = Side length

a = apothem

Area = ½ × ans

Where n = 10, a = 16 and s = 10.4

A = ½ × 16 × 10 × 10.4

A = ½ × 1664

A = 832 m²

Answer:

area = 832 m²

Step-by-step explanation:

the area (A) is calculated as

A = [tex]\frac{1}{2}[/tex] pa ( p is the perimeter and a the apothem )

a decagon has 10 sides , then

p = 10 × 10.4 = 104 m

A = [tex]\frac{1}{2}[/tex] × 104 × 16 = 52 × 16 = 832 m²
