Sarin is to set up the reception area for the anniversary event outside the school hall. The reception area has an area of 45 m2. He used 1/10 of the area is the path, 1/6 of it as the reception counteris and the rest is the guests queuing area. The guests queuing area is divided equally to 4 different queuing lines.
a. What is the area of the reception area used as the guests queuing area?
b. What is the area of the reception area used for each queuing line?
The fraction of area used as guests queuing area = 1 – 1/6 – 1/10 = 44/60 = 11/15
15 units = 45
1 unit = 3m2
The area used as guests queuing area = 11 × 3 = 33m2
The are 4 equal queuing area
The area of each guests queuing line = 33 ÷ 4 = 8 ¼ m2
