Question

Find the breadth of the rectangle whose perimeter is $180cm$ and length is $51cm$.

Answer 1

Breadth of the rectangle

Perimeter of the rectangle $\left(P\right)$ $=$$180cm$

Length of the rectangle $\left(l\right)$ $=$$51cm$

Breadth of the rectangle $\left(b\right)$$=$$\frac{Perimeter}{2}-length$

$$\begin{gathered} =\frac{P}{2}-l \\ =\frac{180}{2}-51 \\ =90-51 \\ =39cm \end{gathered}$$

Therefore, Breadth of the rectangle $\left(b\right)$ is $39cm$.
