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.
