» 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.
​

Answer 1

Given:

The perimeter of a rhombus of side d cm is

`p=4d`

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

`p=4(3.2)`

`p=12.8`

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.

`p=4d`

`14=4d`

Divide both sides by 4.

`(14)/(4)=d`

`3.5=d`

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