Answer:
P = 80
A = 480²
Step-by-step explanation:
To solve for the base we use the Pythagorean Theorem

then we multiply by 2 to get the side length
2x5=10
this is an 8 sided figure with congruent sides so to get the perimeter we multiply 8 and 10
8x10=80 so the perimeter is 80
To find the area of a regular polygon we multiply the apothem (12) and the perimeter (80) and divide by 2
12x80=960
960/2=480
the area is 480²
