A student is attempting to solve a math problem shown below. Which statement best applies to the student’s sample mathematical work?

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

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
