Answer:
Area of the given regular pentagon is 61.5 cm².
Step-by-step explanation:
Area of a regular polygon is given by,
Area =
Here, a = Apothem of the polygon
P = Perimeter of the polygon
Apothem of the regular pentagon given as 4.1 cm.
Side of the pentagon = 6 cm
Perimeter of the pentagon = 5(6)
= 30 cm
Substituting these values in the formula,
Area =
= 61.5 cm²
Therefore, area of the given regular pentagon is 61.5 cm².
29-11=18
18²+18²=p²
324+324=p²
p²=648
p=18√2
That's your answer.
