Answer:
The season will last 4 months after the first month (5 months in total)
Step-by-step explanation:
53 games
9 games first month
11 games per month (since the second one)
x - number of months
9 + 11x = 53
11x = 53-9
11x = 44
x = 4

KN / PD = 54/24 = 2.25
KB / PF = 49.5/22 = 2.25
BN / DF = 40.5/18 = 2.25
ΔKBN ~ PDF (SSS) : two triangles are similar, their corresponding sides are in equal proportion.
