Question

Find the perimeter of the rectangle with the lengths and breadths as follows:

$8.5$ cm and $4$ cm

Answer 1

Given : Length $=8.5$ cm and breadth $=4$cm

As, Perimeter of rectangle $=2\times \left(\text{length×breadth}\right)$

So, Perimeter $=2\times \left(8.5+4\right)$

$$\begin{gathered} =2\times 12.5 \\ =25\mathrm{cm} \end{gathered}$$

Hence, perimeter of rectangle is $25\mathrm{cm}.$
