Question

one side of a parallelogram is 3 by 4 times its adjacent if the perimeter of parallelogram is 70 cm find the side of the parallelogram

Answer 1

Let the side be X cm

Now in a parallelogram opposite sides are equal and parallel.
One more thing is it is given
Y ( the other side ) = 3/4 X cm

So the perimeter of parallelogram is 
2 ( x + y ) = 70
2 ( X + 3/4 X ) = 70
7x / 4 = 35
X = 140 / 7 
X = 20 cm
Y = 3/4 X = 15cm

So the sides of the parallelogram is
20 cm , 20 cm , 15 cm , 15 cm

Answer 2

Answer:

x=20cm ,y=15 cm

Step-by-step explanation:

Let the side be x

perimeter of parallelogram is

2(x+y)=70

2(x+3/4x)=70

7/4x=70/2

7/4x=35

x=35×4/7

x=140/7=20

y=3/4x=3/4×20=15 cm

So, x=20cm

y=15 cm
