Question

The breadth of a rectangular field is twice its length. If the area of the field is 1083 m²,
find the cost of fencing it at 35
per m.​

Answer 1

Answer:

The cost of fencing is Rs.4,886.7

Step-by-step explanation:

Given:

Area of rectangular field = 1083 sq.m.

Here it is given that breadth is twice of its length.

Let length of rectangular field be x m.

So, breadth of rectangular field be 2x m.

Area of rectangular field = length × breadth

                               1083 = x × 2x

                                 $x^{2}$ =1083 /2

                                 x= $\sqrt{541.5}$

                                 x=23.27 m.

Length of rectangular field=23.27 m.

Breadth of rectangular field = 2 × 23.27

                                              =46.54 m.

Perimeter of rectangular field= 2 (length + breadth)

                                                = 2 ( 23.27 + 46.54)

                                                 = 2 × 69.81

                                               = 139.62 m.

Cost of fencing of 1 m.=Rs.35

Cost of fencing of 139.62 m.=35 × 139.62

                                              =4,886.7 RS.
