Final answer:
To calculate the width of the banquet hall, divide the area of the hall by its length, giving a width of 40 meters.
Step-by-step explanation:
To find the width of the rectangular banquet hall with an area of 3600m² and a length of 90m, we can use the formula for the area of a rectangle, which is Area = length × width. The problem gives us the area and the length, so we can rearrange the formula to solve for the width:
- Area = length × width
- 3600m² = 90m × width
- Width = 3600m² / 90m
- Width = 40m
The width of the banquet hall is therefore 40 meters.
