Question

.the diagonals of a rhombus are24cm and10cm find it's area and perimeter​

Answer 1

please mark me brain list

Given that AC = 24 and BD = 10

Because it is rhombus diagonal will bisect each other at right angle.

∴AO=OC=12

and BO=OD=5

In triangle AOB, ∠BOA=90

AB2=122+52=144+25

AB=169−−−√

AB=13

Perimeter of rhombus

=13×4=52cm
