There are a lot of dots but do I you have a question
I tried to count them but I kept losing track
Answer:
I believe it is B! Sorry if I'm incorrect
Take inverse on both sides
i get 74.054
Since a square is equal on all 4 sides, that means each side would be 5, because 20/4=5
so using the Pythagorean thrm (which we can use since a square has all 90 degree angles)
a=5 b=5 c=?
5^2+5^2=c^2
25+25=c^2
50=c^2 *square root both sides*
c= 7.07
So the answer would be 7.1
Three options are 6:8, 9:12, 12:16
