Answer:
Octagon
Step-by-step explanation:
Formula for a polygon is :
- a = apothem (distance from center to the midpoint of a side
- P = perimeter (sum length of the sides)
Since a regular octagon has 8 sides, and a regular hexagon has 6, the octagon will have the greater area due to greater perimeter.

Answer:
-27/8
Step-by-step explanation:
Dividing fractions is the same as multipling the first fraction by the reciprocal of the second fraction (the numerator and denomiator are flipped).
= -3/4 x 9/2
= -27/8
You can simplify this if you want so it's not a mixed fraction
= -3 3/8
