Trapezoid Phase 3

Phase III
My polygon is a trapezoid.The perimeter is B+A+C+C.This trapezoid represents my planet's shape and size.Also the way to find the perimeter of my planet is,A=3 B=4 C=5.First you would do 3A+5C.Then you would do 5C+4B because you had to use two C’S to complete the shape.Then you would do 8+9 because when you do the math you do 3+5=8.Then 5+4=9.Then you would do 8+9=17km.

Some facts on my planet BOB are.There is the same amount of gravity,water (75%),land/grass,and living organisms.On planet BOB if you cut down a tree you have to dig up the rut and plant a new tree there.Also you are allowed to kill only ten animals a year.Plus The oxygen is 1% lower than earths oxygen.Also there is only 3 factoriers so there is less pollution.Even
