Question

Length and breadth of a rectangular field is 5:3. if the breadth of rectangle is 60 m , find the length of the number of rectangle .​

Answer 1

Answer:

Let length =5x and breadth =3x

∴ Area = length × breadth

=5x×3x=15x

2

Cost of cultivating 1 square meter =25 paise

∴ Cost of cultivating 15x

2

square meter =25×15x

2

=375x

paise= Rs.

= Rs. 6000

=

375

6000×100

⇒x

2

=1600

⇒x=40

∴ length =5×40=200 m

and breadth =3×40=120 m

Since, perimeter =2( length + breadth)

=2(200+120)

=2(320)=640 m

hence, option C is correct.
