Question

Find the perimeter of the rectangles whose lengths and breadths are given below,

Length $=$$\text{5 cm}$ , Breadth $=$ $\text{3 cm}$

Answer 1

We have,

Length of the rectangle, l $=$ $\text{5 cm}$

The breadth of the rectangle, b $=$ $\text{3 cm}$

Therefore,

$$\begin{gathered} \text{Perimeter of rectangle=2(l+b)=2(5+3)} \\ \text{=2×8} \\ \text{=16 cm} \end{gathered}$$

Hence, the perimeter of a rectangle is $\text{16 cm}$
