speakers place every 10 yds around the wall of school auditorium. Auditorium is 210 ft by 300 ft. How many wall speakers are placed around the auditorium?
To find the number of wall speakers placed around the auditorium, we need to determine how many speakers can fit on each wall and then calculate based on the dimensions of the auditorium.
1) Calculate the perimeter of the auditorium:
Perimeter = 2 × (Length + Width)
Perimeter = 2 × (210 ft + 300 ft)
Perimeter = 2 × 510 ft
Perimeter = 1020 ft
2) Convert the perimeter from feet to yards since the speakers are placed every 10 yards:
Perimeter in yards = Perimeter in feet / 3
Perimeter in yards = 1020 ft / 3
Perimeter in yards ≈ 340 yds
3) Divide the perimeter in yards by the distance between each speaker:
Number of speakers = Perimeter in yards / Distance between each speaker
Number of speakers = 340 yds / 10 yds
Finally, we can calculate the number of wall speakers:
Number of speakers = 34 speakers
Therefore, around the walls of the school auditorium, there are 34 wall speakers placed.
