80 students of the same height, stand with both hands stretched all along the sides of a rectangular garden, each student covering a length of 1.75 m. Then the perimeter of the garden is____

Options

A. 1400m
B. 140m
C. 14m
D. 1400km

Answer

To find the perimeter of the rectangular garden, we can follow these steps:

### Step 1: Calculate the total length covered by all students.
Since each student covers a length of 1.75 meters and there are 80 students, we can calculate the total length covered by multiplying the number of students by the length each student covers.

\[ \text{Total Length} = \text{Number of Students} \times \text{Length Covered by Each Student} \]
\[ \text{Total Length} = 80 \times 1.75 \]

### Step 2: Perform the multiplication.
Now, we will multiply 80 by 1.75.

\[ 80 \times 1.75 = 140 \text{ meters} \]

### Step 3: Understand the relationship between total length and perimeter.
The total length covered by the students is equal to the perimeter of the rectangular garden. Therefore, we can conclude that:

\[ \text{Perimeter of the garden} = 140 \text{ meters} \]

### Final Answer:
The perimeter of the garden is **140 meters**.
