Question

the length and breadth of a rectangular field are in the ratio 3 ratio 2 is the area of the field is 3456 metre square find the cost of fencing it at rupees 60 per metre​

Answer 1

Step-by-step explanation:

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:

Given:

the length of rectangle :3x

the breath of rectangle:2x

_________________________

$2x \times 3x = 3456$

$6x \: \: = \: \: 3456$

$x \: \: = \: \: \frac{3456}{6}$

$x = 576$

_________________________

Therefore ,

x=24

L = 24*3

=72

B = 24*2

=48

_________________________

perimeter of rectangle:

2(l + b)

=2(72+48)

=2(120)

=240

________________________

( 240) * (160)

= 38400

So that rupees 38400 is needed to fence this rectangular field

Extra related to this:-

Area of rectangle:

product of opposite sides:-

(length)*(breadth)

perimeter of rectangle:

l+l+b+b

=(2l) + (2b)

2 (l + b)
