Vladimir [108]

Answer:

Therefore he can go inside because 55 inches is taller than 54 inches.

Step-by-step explanation:

Converting feet into inches

His height was 52 inches.

He has grown 3 inches

His new height is 52+3 = 55 inches

Therefore he can go inside because 55 inches is taller than 54 inches.
