Question

The length of a rectangular pak is 760m and its breadth is 320m. What will be cost of fencing this park at the rate of RS7.50 per metre?

Answer 1

Has the park given is rectangular. Use perimeter formula to get total length

P=2(length +breadth)

=2(760+320)

=2160m

Cost of fencing = rate * perimeter

=7.50 * 2160

=Rs. 16,200

Answer 2

$\textbf{\underline{\underline{Answer :-}}}$

The money required to Fence the ground is Rs.16200.

$\textbf{\underline{\underline{Explanation :-}}}$

Given :

The Length of the Rectangle = 760m

Breadth of the Rectangle = 320 m

Rate of Fencing = Rs. 7.5

To find :

The money required for Fencing the Rectangular ground

Solution :

First we need to find the Perimeter of the Rectangle

$\star$ Perimeter of Rectangle =

$\boxed{\sf{2(length + breadth)}}$

$\implies$ 2(760 + 320)

$\implies$ 1520 + 640

$\implies$ 2160

The Perimeter is 2160 m

$\star$ Money Required to Fence the ground :

$\implies$ 2160 × 7.5

$\implies$ 16200

$\therefore$ The money required to Fence the ground is Rs.16200.
