The area of a rectangular field is 75 sq.m whose length is 10 m . Find the ratio of breadth to the length of this rectangular field . 

Dear Student,
Please find below the solution to the asked query:

$$\begin{gathered} \mathrm{Let} \mathrm{length} \mathrm{be} \mathrm{L} \mathrm{and} \mathrm{breadth} \mathrm{be} \mathrm{B}. \\ \mathrm{L}=10 \mathrm{m} \\ \mathrm{Area}=75 {\mathrm{m}}^2 \\ \Rightarrow \mathrm{L}\times \mathrm{B}=75 \\ \Rightarrow \mathrm{B}=\frac{75}{\mathrm{L}}=\frac{75}{10}=7.5 \mathrm{m} \\ \mathrm{Hence} \\ \frac{\mathrm{B}}{\mathrm{L}}=\frac{7.5}{10}=\mathbf{0}\mathbf{.}\mathbf{75}\mathbf{ }\left(\mathbf{Answer}\right) \end{gathered}$$
