please give the answer with explaination​

Answer 1

Answer:

If the base and height of a parallelogram are in the ratio 7:3 and the height is 45 cm. ... 4725 cm² is the area of parallelogram

Step-by-step explanation:

Answer 2

Given :

• Base and Height of a parallelogram are in the ratio 7:3 .
• Height of Parallelogram is 45 cm .

To Find :

• Area of Parallelogram .

Solution :

$\longmapsto\tt{Let\:the\:Base\:be=7x}$

$\longmapsto\tt{Let\:the\:Height\:be=3x}$

As Given that Height of Parallelogram is 45 cm . So ,

$\longmapsto\tt{3x=45}$

$\longmapsto\tt{x=\cancel\dfrac{45}{3}}$

$\longmapsto\tt\bf{x=15}$

Value of x is 15 ..

Therefore :

$\longmapsto\tt{Base\:of\:Parallelogram=7(15)}$

$\longmapsto\tt\bf{105\:cm}$

Now ,

For Area :

$\longmapsto\tt{Base=105\:cm}$

$\longmapsto\tt{Height=45\:cm}$

Using Formula :

$\longmapsto\tt\boxed{Area\:of\:Parallelogram=b\times{h}}$

Putting Values :

$\longmapsto\tt{105\times{45}}$

$\longmapsto\tt\bf{4725\:{cm}^{2}}$

So , The Area of Parallelogram is 4725 cm² ..
