Question

the perimeter of rectangular field is 500 m and its length is 150 metre find its breadth its area cost of ploughing the field at rupees 1.20 per square metre​

Answer 1

Step-by-step explanation:

perimeter= 2(l+b)

500m= 2(150+b)

500m= 300+b

500-300=b

200m= b

area = l× b

area = 150×200

= 30000sq.m

cost of ploughing 1sq.m =₹ 1.20

so, cost of 30000sq.m= 1.20×30000

= 36000

Answer 2

Answer:

Step-by-step explanation:

perimeter=500

l=150m

B=?

p=2(l+b)

500=2(150+b)

500=300+b

500-300=b

B=200

area=L×B

AREA=150×200

30000sq.m

cost of ploughing 1sq.m =₹ 1.20

so, cost of 30000sq.m= 1.20×30000

= 36000
