Question

The area of a rectangle of length 7.1 cm is 17.75 sq cm .Find its breadth.

Answer 1

Dear student,

$$\begin{gathered} Areaofrec\tan gle=Length\times Breadth \\ \Rightarrow 17.75=7.1\times B \\ \Rightarrow B=\frac{17.75}{7.1} \\ \Rightarrow B=\frac{1775\times 1\cancel{0}}{71\times 10\cancel{0}} \\ \Rightarrow B=\frac{1775}{71} \\ \Rightarrow B=2.5cm \end{gathered}$$
