QUICK QUESTION - DILATIONS HELP!

The diagram below shows two similar flower beds between intersecting walkways. The third side of each flower bed has a brick border. The perimeter of the big flower bed is 63 feet.


What is the length of the brick border in the small flower bed?

3 feet

2 feet

6 feet

9 feet

Answer 1

Perimeter of large triangle P = L + L + L = 63
but you know two sides so P = 18 + 18 + L = 63

and so your last side is 27

Answer 2

dilations deal with how big one side is to the other so your dilation factor here is 3

Answer 3

How did you get 3? I just want to make sure.. @JAMG

Answer 4

6 * 3 = 18

6 * 3 = 18

s * 3 = 27

Answer 5
