Question

6
If the diagonals of a rhombus are 12 cm
and 16 cm respectively, find its perimeter.​

Answer 1

Answer:

Perimeter of rhombus = 40 cm

Step-by-step explanation:

Let ABCD is a rhombus.

Given that-

The diagonals of a rhombus are 12 cm and 16 cm.

Let AC and BD are the diagonals of rhombus ABCD.

Then AC = 12 cm

BD = 16 cm

Perimeter of rhombus =?

We know that-

$Perimeter \ of \ rhombus \ = 2\sqrt{AC^{2}+BD^{2} }$

Where AC and BD are the diagonals of rhombus.

                                           $= 2\sqrt{16^{2}+12^{2}}$

                                           $= 2\sqrt{256+144}$

                                           $= 2\sqrt{400}$

                                                  = 2×20

                                                  = 40

Perimeter of rhombus = 40 cm
