Hair grows at an average rate of 0.5 inches per month. Courtney refused to cut her hair from the time she was 8 years old until she was 20 years old. If Courtney's hair grew at the
average rate, approximately how many inches did her hair grow during the time she refused
to cut her hair?

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
