Question

» The perimeter of a rhombus of side d 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.

$\dfrac{14}{4}=d$

$3.5=d$

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