look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3

answer: ⇒ d. (7.3)(8.52)=62.19

step-by-step explanation:

product it's going to be multiply by the numbers, fractions, factors, and multiples.

1. (29.5)(1.7)=50.15

2. (13.2)(4.5)= 59.4

3. (4.67)(9.8)= 45.76

4. (7.3)(8.52)= 62.19

hope this !
