Question

the diagonals of rhombus are 20 cm and 21 cm resp.then find the side of the rhombus with neat and labelled daigram​

Answer 1

A)

We know that in a rhombus the diagonals bisect each other at 90

so let AC=20 AND BD=21 CM

AD=10 AND BO=10.5 CM

AB^2=AD^2+OB^2

=10^2+10.5^2

=100+110.25

=210.25

AB=14.5 IS THE SIDE OF THE RHOMBUS

PRIMETER=4S

=4(14.5)

=58 CM
