Step-by-step explanation:

Given :

• Perimeter of parallelogram - 81.2 cm.

• Height - 4 cm.

To find :

• Base of parallelogram .

Solution :

Formula to find perimeter : 2(height + base)

Therefore,perimeter is 81.2 cm and height is 4 cm.

Perimeter of parallelogram = 2(height + base)

... 81.2 = 2(4 + base)

$\frac{81.2}{4} = 20.3 \\ \frac{81.2}{20.3 \times 2}$

$\frac{81.2}{40.6} = 2$
