Question

The adjacent sides of a parallelogram are $5cm$ and $9cm$. Its perimeter is $\_\_\_\_\_\_\_\_.$

Answer 1

Given the length of adjacent sides $5cm$and $9cm$

We know that,

the perimeter of Parallelogram $=2\times$(sum of lengths of adjacent sides)

$$\begin{gathered} =2\times (5+9) \\ =2\times 14 \\ =28cm \end{gathered}$$

Hence, the adjacent sides of a parallelogram are $5cm$ and $9cm$. Its perimeter is $28cm$
