These figures are similar. the perimeter and area of one are given. the perimeter of the other is also given. find its area and round to the nearest tenth tenth.

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: 180

step-by-step explanation:

12-2=10

20-2=18

18x10=180
