Question

Find the cost of erecting a fence around a square field, whose area is 729 hectares at the rate of rupees 1.50 per meter ( 1 hectare =10000 metre square

Answer 1

Answer:

The answer is given as follows;

Step-by-step explanation:

Given, Area of square = 729 hectares

Therefore, Area of square =72900$meter^{2}$

Let the side of the square be x,

=> Area of the square = 72900 $m^{2}$

=> $side^{2}$ = 72900

=> side = $\sqrt{72900}$

=> side =270

Now, length of border=4 x 270

                                    =1080 m

now,

cost of fence of 1 meter square field = Rs 1.50

therefore, cost of fence of 1080 m = 1080 x 1.50

                                                         = Rs 1620.

Answer 2

Step-by-step explanation:

The answer is given as follows;

Step-by-step explanation:

Given, Area of square = 729 hectares

Therefore, Area of square =72900meter^{2}meter2

Let the side of the square be x,

=> Area of the square = 72900 m^{2}m2

=> side^{2}side2 = 72900

=> side = \sqrt{72900}72900

=> side =270

Now, length of border=4 x 270

                                    =1080 m

now,

cost of fence of 1 meter square field = Rs 1.50

therefore, cost of fence of 1080 m = 1080 x 1.50

                                                         = Rs 1620.
