Question

two adjacent sides of a parallelogram is X cm and 4 cm, if its perimeter is 20 cm, find the length of its all sides​

Answer 1

Answer :

Let the adjacent side be 5x and 7x respectively.

Let the adjacent side be 5x and 7x respectively.We know that opposite sides of parallelogram are equal and opposite

Let the adjacent side be 5x and 7x respectively.We know that opposite sides of parallelogram are equal and oppositeSo, 5x+7x+5x+7x=24x [Perimeter]

Let the adjacent side be 5x and 7x respectively.We know that opposite sides of parallelogram are equal and oppositeSo, 5x+7x+5x+7x=24x [Perimeter]Given, 24x=72

Let the adjacent side be 5x and 7x respectively.We know that opposite sides of parallelogram are equal and oppositeSo, 5x+7x+5x+7x=24x [Perimeter]Given, 24x=72x=3

Let the adjacent side be 5x and 7x respectively.We know that opposite sides of parallelogram are equal and oppositeSo, 5x+7x+5x+7x=24x [Perimeter]Given, 24x=72x=3Hence length of sides of parallelogram are 5×3 and 7×3 or 15 cm and 21 cm.

Answer 2

Answer:

Let the adjacent side be 5x and 7x respectively.

We know that opposite sides of parallelogram are equal and opposite

So, 5x+7x+5x+7x=24x [Perimeter]

Given, 24x=72

x=3

Hence length of sides of parallelogram are 5×3 and 7×3 or 15 cm and 21 cm.
