Open in App Solution ## The correct option is C$7200, 856 m Length of the courtyard = 75 m Breadth of the courtyard = 32 m Perimeter of the courtyard = 2 × (75 + 32) m = 2 × 107 m = 214 m Distance covered by the boy in taking 4 rounds = 4 × perimeter of courtyard = 4 × 214 = 856 m We know that area of the courtyard = length × breadth = 75 × 32 m2 = 2400 m2 For 1 m2, the cost of leveling = $3 For 2400 m2, the cost of leveling =$3 × 2400 = \$7200
