Let's denote the breadth of the floor as \( b \) meters. According to the problem, the length of the floor is more than its breadth by 200%. This means the length is 200% of the breadth, or in other words, the length is three times the breadth (since 100% + 200% = 300% = 3 times).

So, we can write the length \( l \) as:
\[ l = 3b \]

We are given that the length \( l \) is 15.491933384829668 meters. Therefore:
\[ 3b = 15.491933384829668 \]

Now, we can solve for \( b \):
\[ b = \frac{15.491933384829668}{3} \]
\[ b = 5.163977794943223 \]

The area \( A \) of the floor can be calculated as:
\[ A = l \times b \]
\[ A = 15.491933384829668 \times 5.163977794943223 \]
\[ A = 79.99999999999999 \] (approximately 80 square meters)

We are given that Rs. 240 is required to paint the entire floor. To find the rate per square meter, we divide the total cost by the total area:
\[ \text{Rate per sq m} = \frac{\text{Total Cost}}{\text{Total Area}} \]
\[ \text{Rate per sq m} = \frac{240}{80} \]
\[ \text{Rate per sq m} = 3 \]

Therefore, the rate per square meter to paint the floor is Rs. 3.
바닥의 너비를 \( b \) 미터로 표시해 보겠습니다. 문제에 따르면 바닥의 길이는 너비보다 200% 더 큽니다. 즉, 길이가 너비의 200%이며, 다른 말로 하면 길이가 너비의 3배입니다(100% + 200% = 300% = 3배이므로).

따라서 길이 \( l \)은 다음과 같이 쓸 수 있습니다:
\[ l = 3b \]

길이 \( l \)은 15.491933384829668미터라고 주어졌습니다. 따라서:
\[ 3b = 15.491933384829668 \]

이제 \( b \)를 풀 수 있습니다:
\[ b = \frac{15.491933384829668}{3} \]
\[ b = 5.163977794943223 \]

바닥의 면적 \( A \)는 다음과 같이 계산할 수 있습니다:
\[ A = l \times b \]
\[ A = 15.491933384829668 \times 5.163977794943223 \]
\[ A = 79.99999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999
