Following is the frequency distribution of total marks scored by the students of different sections of Class \(VIII\).
| Marks | \(100 - 150\) | \(150 - 200\) | \(200 - 300\) | \(300 - 500\) | \(500 - 800\) |
| Number of students | \(30\) | \(90\) | \(140\) | \(80\) | \(120\) |
Find the length of the rectangle of the histogram.
| Marks | Frequency | Width of the class | Length of the rectangle |
| \(100 - 150\) | \(30\) | ||
| \(150 - 200\) | \(90\) | ||
| \(200 - 300\) | \(140\) | ||
| \(300 - 500\) | \(80\) | ||
| \(500 - 800\) | \(120\) |
Construct a histogram for the distribution above.
