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.
