Answer:
Look below
Step-by-step explanation:
Ok, you got a Quadrilateral with the side lengths 6, 9, 9, 12
The shortest of B is 2
Find the scale factor of the A to B
6 -> 2
6/2 = 3
Scale factor is 3
Now divide all the sides by scale factor
6/3, 9/3, 9/3, 12/3 = 2, 3, 3, 4
Add them all together to get the perimeter
2+3+3+4 = 12
Perimeter of B is 12
Triangle b because it only has 3 sides
5km = 5000 meters
450m+800m= 1250m
5000m-1250m= 3,750m
3 3/4 km
The answer is <span>1.082 x 10^<span>8
Hope this helps!!
