38cm

​

Answer 1

Answer:

The perimeter of a parallelogram is 38 cm.

explanation :

The perimeter of a parallelogram=2(a+b)

P=2(12+7)

=2(19)

=38 cm

Answer 2

Given:

The two sides of a parallelogram are 12 cm and 7 cm long.

To find:

The perimeter of the parallelogram.

Solution:

A parallelogram is a form of a quadrilateral having opposite sides parallel to each other.

Let us name the parallelogram PQRS.

The perimeter of PQRS is,

Perimeter = 2× ( a+b )

a and b are the two sides of the parallelogram PQRS.

The sides of PQRS are 12 cm and 7 cm.

Therefore,  

Perimeter = 2 × ( 12+7)

= 2×( 19)

= 38

Hence, the perimeter is 38 cm.
