adjacent sides of a parallelogram are in the ratio 1 ratio 3 and their perimeter is 88 CM then find the length of the side​

Answer»

Answer:-

Given:-

  • RATIO of the adjacent sides of parallelogram are 1 : 3.

  • Perimeter of parallelogram is 88 cm.

To Find:-

  • The length of sides.

Solution:-

Here, Let the ratio constant be x.

Then, One side = x cm

and, Another adjacent side = 3x cm.

Since, We know that opposite sides of parallelogram are equal.

Now, x + x + 3x + 3x = 88 \ cm

⇒  8x = 88 \cm

⇒  x = \dfrac{88}{8}

⇒  x = 11

So, One side = 11 cm

and, Another adjacent side = 3 × 11  

                                               = 33 cm

Some IMPORTANT Terms:-

  • Area of Parallelogram = Base × Height

  • Area of Rectangle = Length × Breadth

  • Perimeter of Rectangle = 2( L + B )
