Question

find the cost of fencing a rectangular field whose length is 12 m and breath is 7 m at rate of rs 5.25 meter​

Answer 1

Given :

• Length and Breadth of a Rectangular park is 12 m and 7 m respectively .

To Find :

• Cost of fencing the park at rate of Rs. 5.25 per m² .

Solution :

$\longmapsto\tt{Length=12\:m}$

$\longmapsto\tt{Breadth=7\:m}$

Using Formula :

$\longmapsto\tt\boxed{Perimeter\:of\:Rectangle=2(l+b)}$

Putting Values :

$\longmapsto\tt{2(12+7)}$

$\longmapsto\tt{2(19)}$

$\longmapsto\tt\bf{38\:m}$

So , The Perimeter of Field is 38 m .

Now ,

$\longmapsto\tt{Cost\:of\:1\:{m}^{2}=Rs.5.25}$

$\longmapsto\tt{Cost\:of\:38\:{m}^{2}=38\times{5.25}}$

$\longmapsto\tt\bf{Rs.199.5}$

So , Cost of Fencing Field at the rate of Rs.5.25 per m² is Rs.199.5 ...
