Samantha is 1.15 m tall on her eleventh birthday and 1.32 m tall on her twelfth birthday. By what factor has her height increased?

To calculate the factor by which Samantha's height has increased, we need to divide her height on her twelfth birthday by her height on her eleventh birthday.

Height factor = Height on twelfth birthday / Height on eleventh birthday

Height on twelfth birthday = 1.32 m
Height on eleventh birthday = 1.15 m

Let's substitute the values into the formula:

Height factor = 1.32 m / 1.15 m

Height factor = 1.1478

Therefore, Samantha's height has increased by a factor of approximately 1.1478.
