Question

The area of a rectangle is 120 cm², If the breadth is 6 cm, then its length is _________.

Answer 1

$$\begin{gathered} \mathrm{We}\mathrm{have}, \\ \mathrm{Area}\mathrm{of}\mathrm{the}\mathrm{rectangle}=120{\mathrm{cm}}^2\mathrm{and} \\ \mathrm{Breadth}\mathrm{of}\mathrm{the}\mathrm{rectangle}=6\mathrm{cm} \\ \mathrm{As},\mathrm{the}\mathrm{length}\mathrm{of}\mathrm{the}\mathrm{rectangle}=\frac{\mathrm{Area}}{\mathrm{Breadth}} \\ =\frac{120}{6} \\ =20\mathrm{cm} \end{gathered}$$

Hence, the length of the rectangle is 20 cm.
