Question

A rectangular field has dimensions 30m *50m. find the cost of fencing the field at the rate of 20₹ per m​

Answer 1

Answer: Rs. 3,600

Step-by-step explanation: l = 30 m

                                             b = 50 m

                                 perimeter = 2(l + b)

                                                      2(30 + 50)

                                                       2(80)

                                                        160 m sq.

               cost of fencing the field = 160 * 20

                                                        =  Rs. 3,200    

Answer 2

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

The Cost of Fencing the Rectangular Field is Rs. 3200.

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

Given :

Length of the Rectangular Field = 50 m

Breadth of the Rectangular Field = 30 m

Rate of Fencing = Rs. 20 per m.

To Find :

Cost of Fencing the Rectangular field

Solution :

Fencing is done on the borders of any particular area. To get the cost of Fencing, find the Perimeter of the Rectangle.

★ Perimeter = $\boxed{\sf{2(Length+Breadth)}}$

$\longrightarrow \: 2(50 + 30)$

$\longrightarrow \: 100 + 60$

$\longrightarrow \: 160$

Perimeter of the Rectangle is 160 m.

$\rule{300}{1.5}$

Cost of Fencing -

Multiply the Rate of Fencing by the Perimeter of the Rectangle.

$\longrightarrow \: 160 \times 20$

$\longrightarrow \: 3200$

$\therefore$ The Cost of Fencing the Rectangular Field is Rs. 3200.
