Given
Ratio of side =3:2
Perimeter =60cm
Altitude =5cm
So let take one side as 3x and other is 2x
Then perimeter of parallelogram
=3x+2x+3x+2x
=10x
According to question perimeter =60cm
Then
10x=60cm
X=60/10=6cm
Then one side is =6 x 3=18
And other is =2x6=12
So base=18cm
Area of parallelogram =bxh
=18x5=90cm²
Altitude corresponding to smaller side
90=12xh
H=7.5cm
