Question

When Miko was 10 years old, she was 135 cm tall. Two years later, her height had increased by 20%. Find Miko's height when she was 12 years old.

Answer 1

Answer: 162 centimeters

1. Firstly change 20% into 0.2

2. Add to height when she was 10 years old, 20% times her height when she was 10:

135 + (0.2 * 135) =
135 + 27 = 162

So Miko’s height when she was 12 years old is equal to 162 centimeters (if you want that is 1.62 meters or about 5’3.78”)
