» The perimeter of a rhombus of side d cm p cm, where p = 4d.
Find the perimeter of a rhombus of
side 3.2 cm.
Find the length of a side of a rhombus
of perimeter 14 cm.

Given:

The perimeter of a rhombus of side d cm  is

To find:

The perimeter of a rhombus of  side 3.2 cm.

Find the length of a side of a rhombus  of perimeter 14 cm.

Solution:

Side of a rhombus is 3.2 cm. So, its perimeter is

Therefore, the perimeter of a rhombus of  side 3.2 cm is 12.8 cm.

The perimeter of another rhombus is 14 cm, and we need find its side.

Divide both sides by 4.

Therefore, the length of a side of a rhombus  of perimeter 14 cm is 3.5 cm.
