Question

The perimeter of a parallelogram
is 42 CM its adjacent sides are in the
ratio 1:2 find the dimensions of the
parallelogram.​

Answer 1

two sides are of 7 cm each and other two are of 14 cm each

Answer 2

Answer:

Solution -

We know,

Perimeter of Parallelogram = 2(length + breadth)

Let's assume one side as x cm

So, the other side be 2x cm

According to Question,

Perimeter of parallelogram = 42 cm

⇒ 2(x + 2x) = 42

⇒ 3x = 42/2 = 21

⇒ x = 21/3

⇒ x = 7

Measurements -

One side = x cm = 7 cm

Another side = 2x cm =2(7) = 14 cm

∴ The adjacent sides of the parallelogram are 7 cm and 14 cm respectively
