Question

The perimeter of a rhombis is 20 cm if one of its diagonal is 6 cm the find the other diagonal and the area of the rhombus

Answer 1

hay mate here is ur ans

in rhombus has all 4 sides are equal

so each side =20/4=5cm

now the diagonals of rhombus bisect each other at 90 degrees

so 1/2*d2=root of (side²-(diagonal /2)²)

=new diagonal =2*(root of (5²-6/2²))=2*root of (25-9)=2*root of 16=2*4=8cm

now area=1/2*d1*d2=1/2*8*6=24cm²

hope it helps you frnd
