Answer: To find the entire parade route, we need to know how many yards the band marched for each of the four sides of the square and then convert those yards to feet.
If the band marched 1,872 yards before their first turn onto Market Street, it means that they also marched 1,872 yards along each of the other three sides of the square.
So the total distance of the parade route in yards is:
1,872 yards + 1,872 yards + 1,872 yards + 1,872 yards = 7,488 yards
To convert that to feet we need to multiply it by 3, since 1 yard equals to 3 feet.
7,488 yards * 3 feet/yard = 22,464 feet
Therefore, the entire parade route was 22,464 feet long.
