Question

In a paralelogram if adjacent sides are 3cm and 4cm then it's perimeter wii be?​

Answer 1

Given:

The adjacent sides of a parallelogram are 3 cm and 4 cm

To find:

The perimeter of the parallelogram

About parallelogram;

• The polygon having four sides.
• The opposite sides are parallel.
• The opposite sides are equal in length.

So,

Two parallel sides will be 3 cm each and

The other two parallel sides will be 4 cm each.

Now,

The perimeter of the parallelogram is

= Sum of all four sides

OR

The perimeter = 2(sum of two adjacent sides)

Thus,

The perimeter of the parallelogram = 3 + 3 + 4 + 4

The perimeter of the parallelogram = 6 + 8

The perimeter of the parallelogram = 14 cm

With another method,

The perimeter of the parallelogram = 2(3 + 4)

The perimeter of the parallelogram = 2*(7)

The perimeter of the parallelogram = 14 cm

Hence,

• The perimeter of the parallelogram is 14 cm

Answer 2

Given:

• ↪ Adjacent Sides of a parallelogram are 3cm and 4 cm

To Find:

• ↪ Perimeter of the parallelogram

Formula Used:

• ↪ Perimeter = 2 ( a + b )

Full Solution:

• Let, 'a' be 3 cm and 'b' be 4 cm

• Applying the formula,

• ➟ Perimeter = 2 ( a + b )

• ➟ Perimeter = 2 ( 3 + 4 )

• ➟ Perimeter = 2 × 7

• ➟ Perimeter = 14 cm

• Hence, the Perimeter of the parallelogram is 14 cm

Extra Information:

• ↪ A parallelogram is a quadrilateral in which opposite sides are parallel.

• ↪ The diagonal of a parallelogram always bisect each other.

• ↪ All the parallelograms are quadrilaterals but all the quadrilaterals are not parallelogram.

• ↪ A parallelogram in which two adjacent Sides are equal is a Rhombus.
