Question

If the length of one side of a rhombus is 7.5 cm then perimeter of the rhombus is

Answer 1

The perimeter of the rhombus is 4a = 7.5 x 4 = 30cm.

Answer 2

It is given one side of a rhombus is 7.5 cm and is asked to give it's perimeter.
So, perimeter of a rhombus = 4a.
In this question, a=7.5.
Therefore, 4a = 4 x 7.5 =30.0 = 30 cm.
Hence, the perimeter of the rhombus of the given length = 30cm respectively.
