The length and breadth of a rectangular courtyard is 75 m and 32 m. Find the cost of leveling it at the rate of $3 per m2. Also, find the distance covered by a boy to take 4 rounds of the courtyard. Choose the correct choice from the following answers:
A) 3573 B) 3455 C) 8600 D) 7000 E) 7200
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 levelling = $3   For 2400 m2, the cost of levelling = $3 × 2400 = $7200 ANSW7200R : 7200
