as we all know ... an octagon has 8 corners / sides

and they told that each side is equal to 2a + 1

so we need to make an equation which will be 8 (2a+1)

ans now we need to multiply 8 with both 2a and 1

so, 8 ( 2a + 1 )

16a + 8

we cant do this further as its not "like"

so the answer is 16a + 8
