24 रूपया /मीटर से खर्च = 5280 रूपया

परिधि = 5280/24 = 220 मीटर

वृत्ताकार खेत की परिधि

2\pi \: r = 220 \\  \\ r =  \frac{220}{2\pi}  \\  \\ r =  \frac{220 \times 7}{2 \times 22} \\  \\  r = 35

इसलिए ,त्रिज्या = 35 मीटर

खेत का क्षेत्रफल =

 = \pi {r}^{2}  \\  \\   = \frac{22}{7}  \times 35 \times 35 \\  \\ =  3850

क्षेत्रफल = 3850 वर्ग मीटर

1 वर्गमीटर जुताई का खर्च = 0.50 रूपया

3850 वर्गमीटर जुताई का खर्च

= 3850 ×0.50

= 1925 रूपया
