Question

Find the perimeter of a rectangle whose length and breadth are $150cm$ and$1m$, respectively.

Answer 1

Finding the perimeter of the rectangle

We have,

Length of the rectangle, l $=$$150cm$

Breadth of rectangle , b $=$$1m$ $=$ $100cm$

Therefore

$$\begin{gathered} \text{Perimeter of rectangle=2(l+b)} \\ \text{=2(150+100)} \\ \text{=2×250} \\ \text{=500 cm} \\ \text{=5 m} \end{gathered}$$

Hence, the perimeter of a rectangle is $500cmor5m$
