hi.. ​

Answer 1

Answer:

Length of a rectangle field =3x

Breadth of a rectangle field =2x

Area =3456 m2

3x×2x=3456 m2

6x2=3456 m2

x2=576 m2

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.60

Cost of 120 meter =Rs.60×120=Rs.720
