A parallelogram has opposites sides equal & parallel

So, in parallelogram ABCD

 

    AB = CD

& BC = AD

Area of parallelogram is

Area of parallelogram = Base × Height

    = b × h

 

Here,

  Base = AB = b

  Height = DE = h

 

Here,

    Base is any side of parallelogram

& Height is perpendicular from opposite vertex to the base

So,

  Area of parallelogram can be written as

Let’s take some examples,

 

Find area of parallelogram

4.jpg

Base = b

 = CD

 = 6 cm

 

Height = h

= BE

       = 3 cm

 

Area of parallelogram = b × h

    = 6 × 3

    = 18 cm 2

 

Find area of parallelogram

5.jpg

Base = b

 = AD

 = 4 m

 

 Height = h

 = BF

 = 4.5 m

 

Area of parallelogram = b × h

    = 4 × 4.5

    = 18 m 2

 

Find area of parallelogram

6.jpg

 

Base = b

= DC

= AB                           (Opposite sides of parallelogram are equal)

= 6 cm

 

Height = h

= BF

= 3 cm

 

Area of parallelogram = b × h

     = 6 × 3

     = 18 cm 2

 

Find area of parallelogram

7.jpg

Base = b

 = AD

 = BC

 = 4.5 m

 

Height = h

 = BF

 = 4 cm

 

Area of parallelogram = b × h

     = 4.5 × 4

                                   = 18 cm 2
