Question

3. If the cost of fencing a rectangular field at Rs. 7.50 per metre is Rs. 600, and the length of the
field is 24 m, then the breadth of the field is​

Answer 1

Answer:

Cost of fencing the rectangular field = Rs. 600

Rate of fencing the field = Rs. 7.50 per m

Therefore, perimeter of the field = Cost of fencing / Rate of fencing = 600 / 7.50 = 80 m

Now, length of the field = 24 m

Therefore, breadth of the field = Perimeter / 2 – Length = 80 / 2- 24 = 16 m

Answer 2

Answer:

breadth will be 16 m.

Step-by-step explanation:

as we know perimeter rectangle =2(l+b)

and rate is ₹7.5/m

so that,

2(24+b)×7.5=600

(48+2b)×7.5=600

360+15b=600

15b=600-360

b=240/15

b =16

therefore the bradgth Will be 16m.
