The answer to the problem above is the fourth triangle. To explain: Triangle 1 has a side length of 50 inches, with Triangle 2 measuring 40 inches as it is 80% of Triangle 1. Triangle 3 then measures 32 inches due to it being 80% of Triangle 2, and Triangle 4 comes down to 25.6 inches, which is 80% of Triangle 3. Hence, Triangle 4 will be the first to have a side length under 29 inches.
