Video Summary

In this problem, a flag measuring 12 cm by 9 cm has quarter circles drawn at each corner. The challenge is to determine the length represented by a question mark in a diagram. By analyzing the equations formed from the rectangle's sides, the sum of the lengths and the equation A + B + C + D + question mark equals 24 contrasts with A + B + C + D equals 18. Subtracting the latter from the former reveals the question mark's value as 6. Therefore, the length indicated by the question mark is 6 centimeters.
