Question

if two sides of parallelogram are 6cm and 4cm find the area of parallelogram​

Answer 1

Answer:

6√ 15 or 23.2379 cm

Step-by-step explanation:

To understand and solve this question, first draw the parallelogram with its diagonal  on a piece of paper. You will see that the parallelogram is divided into two triangles of equal area.

Now Multiply are of one triangle by 2,

We will get,

√ [s (s-a) (s-b) (s-c) ]  x 2

where s = ( 6 + 4 + 8 ) divided by 2

s =  18/2

s = 9 cm.

by substituting the value of s in formula √ [s (s-a) (s-b) (s-c) ]  x 2

we will get,

√ [9 (9-6) (9-4) (9-8) ]  x 2

√[9 x 3 x  5 x 1]  x 2

√135 x 2

6√ 15 or 23.2379 cm

So, the area of parallelogram is 6√ 15 or 23.2379 cm

Answer 2

Answer:

Given : The two sides of the parallelogram ABCD are 6 cm and 4 cm.

To Find :

area of the parallelogram.

Solution :

Refer the attached figure for the diagram of parallelogram ABCD.

The two sides of the parallelogram ABCD,

AB=CD=6 cm

BC=AD=4 cm

Area of the parallelogram is given by,

$\tt{area = base \times height} \\ \tt = ab \times ae \\ \tt = 6 \times 3 \\ \tt= 18 {cm}^{2}$

Area of the parallelogram is 18 cm².
