The length and breadth of a school ground are 150 m and 90 m respectively, while the length and breadth of a mela ground are 210 m and 126 m. respectively. Are these measurements in proportion?

Answer:

Length of school ground \[=150\text{ }m\] Breadth of school ground \[=90\text{ }m\] So, ratio of school ground \[=\frac{150}{90}\]                                     \[=\frac{5}{3}=5:3\] Now, Length of mela ground \[=210\text{ }m\] Breadth of mela ground \[=126\text{ }m\] So, Ratio of mela ground \[=\frac{210}{126}=\frac{5}{3}=5:3\] Therefore, Ratio of school ground = Ratio of mela ground, i.e., \[5:3::5:3\]. So, measurements are in proportion.
