A rectangular park is 110 m long and 70 m wide. Two cross paths, each 6 m wide, are constructed parallel to the sides. If the cost of construction of these paths is ₹ 175 m2, then what is the total cost (in ₹) of construction of these paths?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 182700
Area of rectangle = Length × Breadth
From the figure
Total area of two crossed paths = Area of PQRS + Area of WXYZ - Area of the shaded region
= 110 × 6 + 70 × 6 - 6 × 6
= 660 + 420 - 36
= 1044 m2
Cost of constructing 1 m2 = Rs. 175
Cost of constructing 1044 m2 = 1044 × 175
= Rs. 182,700
