Use the rules for multiplication by powers of 10 to calculate 20 × 100.
a. 20
b. 2,000
c. 200
d. 20,000

c. (3,2,6) is the answer.

true

step-by-step explanation:

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
