Answer 2

Answer:

The lengths of two adjacent sides of the parallelogram are $10 cm$ and $20 cm$.

Step-by-step explanation:

Let the shorter side of the parallelogram be $x$.

As the lengths of two adjacent sides of the parallelogram are in the ratio $1:2$, the longer side of the parallelogram will be $2x$.

As per given data, the perimeter of parallelogram $= 60 cm$.

The perimeter of any parallelogram $= 2(a + b)$

Where, a and b being the two adjacent sides of that parallelogram.

Therefore, $2(x + 2x) = 60$

$2(3x) = 60$

$6x = 60$

$x = 10 cm$.

Hence, the length of shorter side, $x = 10 cm$ and,

            the length of longer side, $2x = 2$ x $10$

                                                            $= 20 cm$.

Thus, $10 cm$ and $20 cm$ are the lengths of two adjacent sides of the parallelogram.
