Answer 1

Step-by-step explanation:

Let the breadth of the field be X m.

The length of the field be 3x m.

Area of field = 7500 m²

According to the question,

$x \times 3x = 7500 \\ = > 3 {x}^{2} = 7500 \\ = > {x}^{2} = \frac{7500}{3} \\ = > {x}^{2} = 2500 \\ = > x = \sqrt{2500} \\ = > x = 50 \: m$

Now, Length of field = 50×3 =150 m

Breadth of field = 50 m

Perimeter of the field

= 2(l+b)

= 2(150+50)

= 2(200)

= 400 m

Now, Cost of fencing the field at Rs 10/m

= 400×10

= Rs 4000
