On the leeward side of the island of Oahu, in a small village, about 80% of the residents are of the Hawaiian ancestry. Let n=1,2,3… represent the number of people you will meet until you encounter the first Hawaiian ancestry in the village

( ͡° ͜ʖ ͡° ) copy and   paste it

step-by-step explanation:

i think the length is 12 and the width is 17

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
