The length of a rectangular hall is 5 m less than 4 times the breadth of the hall. What is the length, if breadth is x metres?

Answer

To find the length of the rectangular hall based on the given information, we can follow these steps:

### Step 1: Understand the relationship between length and breadth
The problem states that the length of the hall is "5 m less than 4 times the breadth."

### Step 2: Define the variables
Let:
- Breadth of the hall = \( x \) meters (as given in the question)
- Length of the hall = \( L \) meters (which we need to find)

### Step 3: Write the equation based on the relationship
According to the problem, we can express the length \( L \) in terms of the breadth \( x \):
\[ L = 4x - 5 \]
This equation states that the length is equal to 4 times the breadth minus 5 meters.

### Step 4: Conclusion
Thus, the length of the hall when the breadth is \( x \) meters is:
\[ L = 4x - 5 \text{ meters} \]
