Answer: 40 m
Step-by-step explanation:
Width of the rectangular field, w = 27 m
Total cost of fencing = ₹ 1273
Rate of fencing = ₹ 9.5 / m
∴, perimeter of the field = (1273 ÷ 9.5) m
= 134 m
If l (in m) is the length, then
2 ( l + w ) = 134
⇒ l + 27 = 67
⇒ l = 40
Thus, the length of the ground is 40 m.
