From the set {22, 33, 66}, use substitution to determine which value of x makes the inequality true.

A. 22
B. 66
C. 33
D. none of these

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
