Question

find the cost fencing a rectangle park of the lenght 125m and breath 80m at the rate of rupees 15 per​

Answer 1

Given :

• Length and Breadth of a Rectangular park is 125 m and 80 m respectively .

To Find :

• Cost of fencing the park at rate of Rs. 15 per m² .

Solution :

$\longmapsto\tt{Length=125\:m}$

$\longmapsto\tt{Breadth=80\:m}$

Using Formula :

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

Putting Values :

$\longmapsto\tt{2(125+80)}$

$\longmapsto\tt{2(205)}$

$\longmapsto\tt\bf{410\:m}$

So , The Perimeter of Park is 410 m .

Now ,

$\longmapsto\tt{Cost\:of\:1\:{m}^{2}=Rs.15}$

$\longmapsto\tt{Cost\:of\:410\:{m}^{2}=410\times{15}}$

$\longmapsto\tt\bf{Rs.6150}$

So , Cost of Fencing Perk at the rate of Rs.15 per m² is Rs.6150 ...

Answer 2

$\huge{\underline{\underline{Given}}}$

• Length = 125m
• Breadth = 80m

$\huge{\underline{\underline{Solution}}}$

$\boxed{Perimeter\: of\: rectangle = 2(l + b)}$

⟹ $\sf{2(125 + 80)}$

⟹ $\sf{2 × 205}$

⟹ $\sf{410m}$

$\therefore{Perimeter\: of\: the\: park = 410m}$

Now,

★ Rate of fencing per meter is Rs15.

Cost of fencing the park

⟹ $\sf{410 × 15}$

⟹ $\sf{Rs6,150}$

Hence, the cost of fencing the park is Rs6,150
