Question

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

Answer 1

Answer:

Step-by-step explanation:

Area-500m

Length-150m

2(150±b)=500

150±b=500/2=250

b=250-150

b=100m

Cost of ploughing the feild=₹1.20/m^2

Area=l×b

150×100=15000m^2

Cost=15000×1.20

=18000

Cost is ₹18000

Answer 2

Answer:

Step-by-step explanation: Perimeter of rectangular field = 2( l+b )

Perimeter given = 500 m

2( l+b) = 500 m

2( 150 + b ) = 500

2 x 150 + 2 x b = 500

300 + 2b = 500

2b = 500-300

2b = 200

b = 200/2

b = 100 m

Area = l x b

= 150 x 100

= 15000 m^2

Rate = Rs.1.20 / m^2

Cost of ploughing = 15000 x 1.20

= Rs. 18000
