Answer 1

Answer:

ANSWER

Given that:

Length of a rectangle field =3x

Breadth of a rectangle field =2x

Area =3456 m

2

3x×2x=3456 m

2

6x

2

=3456 m

2

x

2

=576 m

2

x=24 m

Therefore, the length =72 m

Breadth =48 m

Perimeter of the rectangular field =72+48=120 m

Cost of 1 meter =Rs.4

Cost of 120 meter =Rs.4×120=Rs.480.

This is the required solution.

Answer 2

Answer:

3750m^2

Step-by-step explanation:

let the sides be 3x and 2x respectively

perimeter = 2(l+b)

= 2(3x+2x) = 250m

= 2× 5x = 250

= 10x = 250

x = 25m

so,

3x = 75m

2x = 50m

now,

area = l×b

= 75×50

= 3750m ^2
