Final Answer:
The number of people that can fit into a square block with a length of 124 feet is 38,416.
Step-by-step explanation:
To determine how many people can fit into a square block with a length of 124 feet, we'll use the information given: 5 people fit into a 4ft x 4ft rectangle. First, calculate the area of the 4ft x 4ft rectangle:
Area = Length x Width = 4 feet x 4 feet = 16 square feet
Now, determine the area of the larger square block with a length of 124 feet:
Area of larger square block = Length x Length = 124 feet x 124 feet = 15,376 square feet
Next, find out how many times the smaller rectangle can fit into the larger square block by dividing their areas:
Number of smaller rectangles in larger square = Area of larger square block / Area of smaller rectangle
Number of smaller rectangles in larger square = 15,376 square feet / 16 square feet = 961
Finally, since each smaller rectangle can accommodate 5 people, multiply the number of smaller rectangles by 5 to find the total number of people that can fit:
Total number of people = Number of smaller rectangles in larger square x People per smaller rectangle
Total number of people = 961 x 5 = 4,805
Therefore, in a square block with a length of 124 feet, 4,805 people can fit.
Please note: It's important to consider practical constraints such as the need for pathways, space for amenities, and other structures that would reduce the actual number of people the block can accommodate. This calculation assumes the entire space is available for people without any obstructions.
