Answer:
Rs 782.25
Step-by-step explanation:
Area of the plot = 40m×30 m =120 square metre.
Area of flower beds = 2.5 m× 2.5m =6.25 square metre
Area of left portion = 120 square metre - (5×6.25)square metre
120-31.25 metric square
88.75 metric square .
cost of ploughing 1 sq.m = rs.25
cost of ploughing 31.25 sq.m = rs.25 ×31.25=Rs 781.25
