Meera went to a rectangular park 140 m long and 90 m wide. She took 5 complete rounds on its boundary. What is the distance covered by her?

Answer

To solve the problem of how far Meera traveled while walking around the rectangular park, we can follow these steps:

### Step 1: Understand the dimensions of the park
The park is rectangular with the following dimensions:
- Length (l) = 140 meters
- Width (b) = 90 meters

### Step 2: Calculate the perimeter of the rectangle
The perimeter (P) of a rectangle can be calculated using the formula:
\[ P = 2 \times (l + b) \]

Substituting the values:
\[ P = 2 \times (140 + 90) \]

### Step 3: Simplify the expression inside the parentheses
First, calculate the sum of the length and width:
\[ 140 + 90 = 230 \]

### Step 4: Multiply by 2 to find the perimeter
Now, substitute back into the perimeter formula:
\[ P = 2 \times 230 = 460 \text{ meters} \]

This means that Meera covers 460 meters in one complete round around the park.

### Step 5: Calculate the total distance for 5 rounds
Since Meera took 5 complete rounds, we multiply the perimeter by 5:
\[ \text{Total Distance} = 5 \times 460 \]

### Step 6: Perform the multiplication
Calculating the total distance:
\[ 5 \times 460 = 2300 \text{ meters} \]

### Final Answer
The total distance covered by Meera after 5 rounds around the park is **2300 meters**.
