10 m
Step-by-step explanation:
A square has all equal side lengths. If that is the case, the we have 4 sides that equal each other:

Answer:
What is the cost of 1 hotdog?
Answer: $4.50
How many hotdogs can you buy for $18?
Answer: 4
Step-by-step explanation:
If $27 can buy you 6 hot dogs, to find the cost of one, we just divide.
27 divided by 6 = 4.5 ($4.50)
So 1 hotdog costs $4.50
If 1 hotdog is $4.50, and we want to know how much we can buy for $18, then we divide again.
18 divided by 4.5 = 4
So for $18, we can buy 4 hotdogs
