Question

The perimeter of a parallelogram whose parallel sides have lengths equal to 13cm and 6cm is_____ *

Answer 1

Answer:

38

Step-by-step explanation:

Perimeter of a parallelogram = Sum of all the side

= 2(a+b)

=2(13+6)

=2 (19)

= 38

Answer 2

✬ Perimeter = 38 cm ✬

Step-by-step explanation:

Given:

• Length of parallel sides of a parallelogram are 13 cm and 6 cm respectively.

To Find:

• What is the perimeter of parallelogram ?

Solution: Let ABCD be a parallelogram where,

• AB || CD and BC || AD
• AB = 13 cm and BC = 6 cm

As we know that opposite sides of a parallelogram are equal and also parallel to each other. Therefore,

• AB = CD = 13 cm
• BC = AD = 6 cm

★Perimeter of ||gm = Sum of all sides★

$\implies{\rm }$ Perimeter = AB + BC + CD + DA

$\implies{\rm }$ 13 + 6 + 13 + 6

$\implies{\rm }$ 19 + 19

$\implies{\rm }$ 38 cm

Hence, the perimeter of parallelogram is 38 cm.

[ We can also find perimeter by using ]

★ Perimeter = 2(Sum of adjacent sides)

$\implies{\rm }$ Perimeter = 2(13 + 6)

$\implies{\rm }$ 2(19)

$\implies{\rm }$ 38 cm

So, Perimeter is 38 cm.
