Question

The length and breadth of a rectangular field are in the ratio of 3:2. If the area of the field is 3456 sq m. Find the cost of fencing the field at rupees 4 per metre ​

Answer 1

Answer: HEY MATE!!!❤❤❤HERE'S UR ANSWER!!! ❤❤❤

LENGTH AND BREADTH OF THE RECTANGULAR FIELD ARE IN THE RATIO 3:2.

i.e.

LENGTH :BREADTH=3:2

LET THE COMMON MULTIPLE BE x

Then,

3:2=3x:2x

AREA OF THE RECTANGLE =LENGTH ×BREDTH.

3456sq.m=(3x) (2x)

6x2=3456

x=24

length,l =3x=72m

breadth,b=2x=48m

perimeter = 240m

​cost of fencing the rectangular field = Rs.14400

HOPE THIS HELPS YOU!!! ❤❤

Answer 2

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
