Before the celebration for
Groundhog Day, the city
set up an octagonal
barrier around the park. If
each side of the barrier
was 145 2/3 yards long,
how many feet of fencing
were used to create the
barrier2

Solution:

8-sided shape is called an octagon

The city  set up an octagonal  barrier around the park

Each side of the barrier  was 145 2/3 yards long

Convert yards to feet

1 yard = 3 foot

Therefore,

How many feet of fencing  were used to create the  barrier

1 side = 437 foot

8 sides = 8 x 437 = 3496 feet

Thus 3496 feet of fencing were used to create the barrier
