Answer 1

Given:

Perimeter of a parallelogram = 64 cm

Length = 3 times larger than the width

To find:

The length of the parallelogram.

Solution:

We know that, the perimeter of the parallelogram is:

`P=2(l+w)`

Where, l is length and w is width of the parallelogram.

We have, l = 3w and P=64.

So,

`64=2(3w+w)`

`64=2(4w)`

`64=8w`

Divide both sides by 8.

`8=w`

Now,

`l=3w`

`l=3(8)`

`l=24`

Therefore, the length of the parallelogram is 24 cm.
