A) 137 customers allowed based on 15 sq ft per person.
B) Decorations need to be 11 feet long to reach across tables and drink station.
A) Customer Capacity:
Based on the image you've sent, here's how to determine the number of customers allowed in the cafe under the new fire code:
1. Calculate the total floor space:
First, identify the dimensions of each rectangular area. From the image, we can find:
Floor Space A: 190 feet x 11 feet = 2090 square feet
Table 1: 5 feet x 3 feet = 15 square feet
Table 2: 3 feet x 5 feet = 15 square feet
Drink Station D:** 3 feet x 4 feet = 12 square feet
2. Subtract the area occupied by furniture:
Subtract the areas of tables and the drink station from the total floor space:
2090 sq ft - 15 sq ft - 15 sq ft - 12 sq ft = 2058 sq ft
3. Divide the remaining space by the required area per customer:
Assuming 15 sq ft of free space per customer, divide the remaining space by 15:
2058 sq ft / 15 sq ft/customer = 137.2 customers
Therefore, under the new fire code, the cafe can accommodate approximately 137 customers.
B) Decoration Length:
1. Table 1: Measure the table's width from the image: 5 feet.
2. Table 2: Measure the table's width from the image: 3 feet.
3. Drink Station: Measure the drink station's width from the image: 3 feet.
4. Total decoration length: Add the widths of all three: 5 ft + 3 ft + 3 ft = 11 feet.
Therefore, the decorations need to be 11 feet long to reach across all the tables and the drink station.
