Question

one side parellogram is 3/4 times its adjacent side. if the perimeter of parellogram is 70 cm. find one side of parellogram .​

Answer 1

Answer:

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
