Use a ruler. I can't see the picture.
Well, 18 yards is 54 feet.
Alright so if I do remember my math correctly, this is how it goes:
- y = -x^2 + x + 3
- x = -b/2a
- x = -1/2(-1)
- x = -1/-2, which = (1/2)
Not quite sure if this was correct, but if it was, hope this helps and you're welcome! :)
the answers is
1 Inch = 4 Feet
Here is the explanation -
the side of square = 12
length of Ground - 48
ratio of length = 12 /48
= 1/4
1 : 4
