1.   2.

Step-by-step explanation:

1. The area of a hexagon is A =

Here our a is 4, so plugging in 4 to our equation gives which simplifies to

2. The area of an octagon is

Here our r is 9, so plugging in 9 to our equation gives which simplifies to

b. b < 1 might be the correct answer

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
