Answer 2

Answer:

We can find answer by finding perimeter of the rectangular garden.

Cost=1960

Step-by-step explanation:

Let the length of the garden = 4x and breath =3x

Area of garden = l*b

4800 = 4x*3x

4800 = 12x^2

4800/12 = x^2

400 = x^2

20^2= x^2

20 = x

or x=20m

lenght = 4x= 4*20= 80m

breath = 3x= 3*20 = 60m

Perimeter of garden = 2(l+b)

= 2(80+60)

= 280m

Wire fencing is four times of it's perimeter

so,

total lenght of wire = 4* 280= 1120m

Cost = 1120*1.75= 1960
