Question

Find the missing value Height=15cm, Base=?,Areaof parallelogram=154.5cm². *

10.3cm

20.6cm

15.6cm

​

Answer 1

Given that :

• Height =15cm
• Area of parallelogram = 154.5cm²

To find :

• The value of Base of the parallelogram.

Solution :

We know that,to find the area of a parallelogram we apply the formula:

$\sf\blue{Area\:of\: parallelogram= Base}\sf\blue\times\blue{Height}$

Putting the values:

$\sf\leadsto{154.5=15}\times{B}$

(Let Base of the parallelogram as B)

$\leadsto\sf\cancel\dfrac{154.5}{15}=B$

$\sf\leadsto{10.3=Base}$

Hence,the value of Base of the given parallelogram is $\sf{10.3cm}$

Therefore, Option a) i.e. $\sf{10.3cm}$ is correct.

Answer 2

Answer:

Given :Height =15cm

Area of parallelogram = 154.5cm²

To find :The value of Base of the parallelogram.

Solution :

We know that,to find the area of a parallelogram we apply the formula:

$\sf\blue{Area\:of\: parallelogram= Base}\sf\times\blue{Height}$

Putting the values:

$\sf\leadsto{154.5=15}\times{B}$

(Let Base of the parallelogram as B)

$\leadsto\sf\cancel\dfrac{154.5}{15}$

⇝10.3=Base

Hence,the value of Base of the given parallelogram is 10.3cm

Therefore, Option a) i.e. 10.3cm is correct
