Answer 1

$\mathfrak{\large{\underline{\underline{Correct\:\:Question :-}}}}$

A square lawn has a side of 28 metre find the cost of fencing it at the rate of rupees 12 per metre.

$\mathfrak{\large{\underline{\underline{Answer :-}}}}$

The Cost of Fencing is Rs.1,344.

$\mathfrak{\large{\underline{\underline{Explanation :-}}}}$

Given :

Measure of the side of the Square = 28 m

Fencing rate = Rs. 12 per metre

To Find :

The Cost of Fencing

Solution :

Fencing is done on the boundary of a particular area. To get the Fencing cost, first find the Perimeter of the Square.

★ Perimeter = $\boxed{\sf{Side \times 4}}$

$\longrightarrow$ 28 × 4

$\longrightarrow$ 112

Perimeter of the Square is 112 m

$\rule{300}{1.5}$

Multiply the rate of Fencing by the Perimeter to get the cost of Fencing.

$\longrightarrow$ 12 × 112

$\longrightarrow$ 1344

$\therefore$ The Cost of Fencing is Rs.1,344.

Answer 2

Answer:-

Using the formula:-

Perimeter =Side×4

=28 × 4

=112

• 112 m is the Perimeter of the Square

=12 × 112

=1344

• Hence,1,344 is the Cost of Fencing.
