Total cost of cultivating a rectangular field at ₹ 15 = ₹ 18330
Therefore, area of field = 18330/15
= 1222 m2
Let the length of the field be L m.
Area = L * B
1222 = L * 26
L = 1222 / 26 = 47 m
Now, perimeter = 2 (L + B)
= 2 (47 + 26) = 2 * 73 = 146 m
Therefore,
Cost of fencing the field = ₹ (146 * 20)
= ₹ 2920
Therefore, area of field = 18330/15
= 1222 m2
Let the length of the field be L m.
Area = L * B
1222 = L * 26
L = 1222 / 26 = 47 m
Now, perimeter = 2 (L + B)
= 2 (47 + 26) = 2 * 73 = 146 m
Therefore,
Cost of fencing the field = ₹ (146 * 20)
= ₹ 2920
