find the width of rectangular. field whose length is 1800 cm and area is 216m

Solution :

Assuming the area of the field is 216 m² ​​​​​​.

Here is the answer accordingly :

$$\begin{gathered} \mathrm{Length} \mathrm{of} \mathrm{the} \mathrm{field}, \mathrm{l} = 1800 \mathrm{cm} = 18 \mathrm{m} \left[\mathrm{as}, 1 \mathrm{m} = 100 \mathrm{cm}\right] \\ \mathrm{Breadth} \mathrm{of} \mathrm{the} \mathrm{field}, \mathrm{b} = ? \\ \mathrm{Area} \mathrm{of} \mathrm{rectangular} \mathrm{field} = 216 {\mathrm{m}}^2 \\ \Rightarrow \mathrm{l} \times \mathrm{b} = 216 \\ \Rightarrow 18 \times \mathrm{b} = 216 \\ \Rightarrow \mathrm{b} = \frac{216}{18} = 12 \\ \mathrm{So}, \mathrm{width} \mathrm{of} \mathrm{the} \mathrm{rectangular} \mathrm{field} = 12 \mathrm{m} = 1200 \mathrm{cm} \end{gathered}$$
