Question 20
Two squares A and B stand next to each other with their bottom edges aligned, as shown. Their total area is 74 square centimeters. Assuming both side lengths are whole numbers of centimeters, find the perimeter of the combined figure in centimeters.
The source implicitly tests whole-number side lengths but does not state that restriction. It is made explicit before answering; without it, the result is underdetermined.
