respectively.
the area of
the park and the cost of
Planting grass in
it at rupess 20 per
m2​

Answer 1

Given :

• Length and Breadth of Rectangle are 75 m and 40 m respectively.

To Find :

• Area of Park .
• Cost of Planting grass at ₹20 per m².

Solution :

$\longmapsto\tt{Length=75m}$

$\longmapsto\tt{Breadth=40m}$

Using Formula :

$\longmapsto\tt\boxed{Area\:of\:Rectangle=length\times{breadth}}$

Putting Values :

$\longmapsto\tt{75\times{40}}$

$\longmapsto\tt\bf{3000{m}^{2}}$

So , The Area of Rectangular Park is 3000m²..

Now ,

Cost of planting grass at ₹20 per m² :

$\longmapsto\tt{3000\times{20}}$

$\longmapsto\tt\bf{Rs.60000}$

Therefore , The cost of planting grass in the park is Rs. 60000..
