Breadth of the hall (in meters) | 10 | \(\square\) | 40 |
---|---|---|---|
Length of the hall (in meters) | 25 | 50 | \(\square\) |
Ratio of breadth to length \(= 2 : 5 = \frac{2}{5}\)
∴ Other equivalent ratios are \(=\frac{ 2}{5} ×\frac{ 10}{10} =\frac{ 20}{50}, \frac{2}{5} × \frac{20}{20} \)
\(= \frac{40}{100}\)
Thus,
Breadth of the hall (in meters) | 10 | 20 | 40 |
---|---|---|---|
Length of the hall (in meters) | 25 | 50 | 100 |
