Question

a rhombus has diagonals of length 8cm and 6cm. find its perimeter.​

Answer 1

We know that in a rhombus, the diagonals bisect each other at right angles

So by applying Pythagoras theorem, we get the side of rhombus as

$\sqrt{4^{2} + 3^{2} }$ = 5 cm

Hence the perimeter = 4×5

                                   = 20 cm
