Question

Find the perimeter of the following rectangles ,if : length $=30\text{cm ,}$ breadth $=25\text{cm}$

Answer 1

Finding the perimeter of the rectangle

We know that, perimeter of the rectangle $=2(\text{l+b)}$, where $\text{l=length , b= breadth}$

Given, length $=30\text{cm ,}$ breadth $=25\text{cm}$

Therefore,

Perimeter of the rectangle $=2(30+25)$

$$\begin{gathered} =2\left(55\right) \\ =110\text{cm} \end{gathered}$$

Hence, perimeter of the rectangle is $\text{110 cm}$ .
