A museum exhibit hall is the shape of a regular octagon. The distance between any two parallel walls is 30 feet. What is the perimeter of the exhibit hall, rounded to the nearest foot? A 80FT
B 84FT
C 99FT
D 105 FT

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
