Question

Perimeter of a rhombus is 180cm and one of its diagonals is 72 . Find the lenght of the other diagnal and area of the rhombus

Answer 1

Step-by-step explanation:

see,perimeter is180

then,length of sides will be 45

now,diagonal is 72 and is bisected into 36 each

then the other diagonal is 2*√(45^2-36^2)

which is 54

now the area is 54*72/2=1944
