Question

The length and breadth of a rectangular field are in the ratio 5: 1. If its breadth is
60 find the cost of fencing it at 40 per metre.​

Answer 1

Answer:

if breath =60

length =5*60

=300 m

perimeter =2(l+b)

2(60+300)

2*360

=720 rs

Answer 2

Answer:

GIVEN :

=> DIMENSIONS OF A RECTANGULAR FIELD :

BREADTH :

=> 60 M

______________________________

THE RATIO OF LENGTH : BREADTH ;

=> 5 : 1

_____________________________

FROM THE INFO :

=> 5 / 1 = LENGTH / BREADTH

=> 5 / 1 = LENGTH / 60 M

=> LENGTH. * 1 = 60 * 5 M

=> LENGTH = 300 M

_____________________________

TO FIND :

=> THE COST OF FENCING

_____________________________

FOR IT,

=> WE HAVE TO CALCULATE THE PERIMETER OF THAT FIELD

_____________________________

PERIMETER OF A RECTANGULAR FIELD ( RECTANGLE )

=> 2 ( LENGTH + BREADTH

=> 2 ( 300 M + 60 M )

=> 600 M + 120 M

=> 720 M

______________________________

COST OF FENCING ;

=> RS 40 PER M

______________________________

COST OF FENCING :

=> PERIMETER OF THAT FIELD * COST OF FENCING PER M

=> 720 M * 40 RS

=> 28,800 RS
