Video Summary

Ahmad and Jaleh start at point A, moving around square and rectangular gardens, respectively, at the same speed. To meet back at A, they need to cover equal distances. The square garden has a perimeter of 20 meters, while the rectangle's is 30 meters. To find when they meet, we calculate the least common multiple of 20 and 30, which is 60 meters. Ahmad must complete 60 meters around his square garden, dividing this by the perimeter (20 meters) to find the number of laps. Ahmad makes 3 laps to meet Jaleh at point A. The answer is 3 laps.
