Using proportions, it is found that the fence should be 19 yards away from point A.
What is a proportion?
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Researching this problem on the internet, the end of Callie's home and the beginning of the neighbor home are 18 yards away, hence the distance should be of:
18/2 = 9 yards.
However, point A is 10 yards from the end of Callie's home, hence the fence should be 19 yards away from point A, as 10 + 9 = 19 yards.
