Question 1. Asked on :05 February 2019:05:11:52 PM

 

The perimeter of a parallelogram is 60 cm and the ratio of its adjacent sides is 3:2 .If the altitude corresponding is 5 cm. Find the area of the parallelogram and the alyitude corresponding to the smaller side

-Added by Himanshi Verma Mathematics » Perimeter And Area

Answer:

Himanshi Verma

 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
