Given pyramid with octagonal base. Image of the pyramid attached below:
We know the formula of Lateral Area of pyramid = 
where p represent the perimeter of the octagonal base
and l represent the slant height of the pyramid.
109.9 = 
Solve for p
p = 32.81 cm
Perimeter of octagonal base (all sides are same) = 8*s
where s represent the side of octagon
8s = 32.81
Solve for s
s = 4.1 cm
Side of the octagon = 4.1cm (option D)

Answer:
6 laps.
Step-by-step explanation:
On Monday she runs 2x + 8 miles, where x miles = the length of the trail.
On Tuesday she runs 4x + 4 miles and this is the same distance as Monday, so
2x + 8 = 4x + 4
4 = 2x
x = 2 miles which is the length of the trail.
So each day she runs 4(2) + 4 = 12 miles.
So on Saturday she runs 12/ 2 = 6 laps.
I personally don’t know the answer so i can’t help
