Question

The perimeter of a regular octagon is 24a + 48 inches.(a) write an expression for the length of any one side of the octagon. The perimeter of a regular octagon is 18 feet.(b)what is the value of a? (C) find the length of each side of the octagon

Answer 1

Answer:

3a+6

Step-by-step explanation:

3a+6 = 24a+48 divided by 8 (there are 8 sides in an octagon)

covert 24a +48 inches into feet

2a+4 feet = 18 feet

subtract 4 from both sides

2a = 14

divided 2 from both sides

a = 7

covert 3a+6 inches into feet

0.25a +0,5

0.25(7)+0.5

= 2.25

verify your answer

2.25 x 8 = 18
