Question

the perimeter of the parallelogram is 60 cm and the ratio of its adjective side is 3 : 4 if the altitude cross ponding too large sige of the parallelogram is 5 cm find the area of the parallelogram and altitude corresponding to the smaller size​

Answer 1

Answer:

Step-by-step explanation:

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
