Answer:
68%
Step-by-step explanation:
Calculate percentage change
from V1 = 82 to V2 = 138
(V2−V1)|V1|×100
=(138−82)|82|×100
=5682×100
=0.682927×100
=68.2927%change
=68.2927%increase
=68%
Apothem is the height of a triangel formed by two consecutive vertices with the center. the are of this triangle = 1/2 s 8 = 4s
there area 12 such triangles in the regular 12 side polygon
So area = 12 * 4 s = 48 s
I don’t know the rest but number seven is n
The answer would be 108 ft^2
