Answer 1

Answer:

perimeter of the rectangular field is 500 m

breadth=220 m

let length x m

then,

2(x+220)=500

=> x+220=500/2

=> x+220=250

=> x=250-220

=> x=30 m

so,length of the rectangular field is 30 m

cost of fencing the field at the rate of Rs 20 per m is

Rs 20×500 =Rs 1000

Answer 2

Answer:

30m, 10, 000

Step-by-step explanation:

perimeter of rectangle field=500 m

breadth of rectangle =220m

Length of rectangle field = x m= 2(x+220) =500

= x +200=500/2

= x=220 = 250

= x= 250 -220

so the length of rectangle field = x= 30m

cost of fencing the field at the rate of 20 per metre = rate × Perimeter

= 20x 500

= RS 10,000
