Angela is 4 cm taller than Helen. Helen is 3 cm taller than Amy. If Amy is 150 cm tall, how many centimeters tall is Angela? Give me reasons, before answering the question
Amy's height is 150 cm. Being 3 cm taller than Amy, Helen's height is 150 + 3 = 153 cm. Being 4 cm taller than Helen, Angela's height is 153 + 4 = 157 cm. So the final answer is 157.
