Question

The shorter side of a parallelogram is 3.6 cm and the longer side is half as much again as the shorter side . Find the perimeter of the parallelogram .​

Answer 1

Answer:

Step-by-step explanation:

shorter side= 3.6

longer side= 3.6/2

=1.8

perimeter=2[l+b]

2[3.6+1.8]

=10.8cm

Answer 2

✬ Perimeter = 10.8 cm ✬

Step-by-step explanation:

Given:

• Shorter side of a parallogram is 3.6 cm.
• Longer side of parallogram is half of shorter side.

To Find:

• What is the perimeter of the parallogram ?

Solution: Length of longer side of parallogram

➭ Longer side = 3.6/2

➭ Longer side = 1.8 cm.

As we know that -

★ Perimeter of Parallogram = 2 ( sum of length of adjacent sides ) ★

• Here, a = 3.6 cm and b = 1.8 cm

$\small\implies{\sf }$ Perimeter = 2 ( 3.6 + 1.8 ) cm

$\small\implies{\sf }$ Perimeter = 2 x 5.4 cm

$\small\implies{\sf }$ Perimeter = 10.8 cm

Hence, the perimeter of parallogram is 10.8 cm.
