well i believe the answer is 142 not 3 i just took the test i put 3 but i failed i think the answer will be 142 more white tiles.

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

answer: 193

explanation:

200-7 = 193
