Which of the following changes should she make to the dimensions to correct her error?
Answer

change the length of side CB to 8 feet

change the length of side RQ to 13 feet

change the length of side CB to 11 feet

change the length of side RQ to 8.5 feet

Answer 1

ratio of their dimensions is constant.
we have PR/AC = PQ/AB = 1.25
but RQ/CB = 1.111

so RQ or CB has to be changed.

below satisfies :
change the length of side CB to 8 feet
