A rectangular grass field has a length of 85 meters and breadth of 65 meters. It is surrounded by a 5-meter wide path. Find the area of the Path and the cost of constructing it at Rs. 5 per square meter?
Answer & explanation
Correct answer: option 4
Area of the path = Area of grass field including the path - Area of the grass field
Area of the path = (85 + 5 + 5 x 65 + 5 + 5) - (85 x 65)
Area of the path = (95 x 85) - (85 x 65)
Area of the path = 8075 - 5525
Area of the path = 2550 cm2
Cost of constructing the path at Rs. 5 per square meter is 2550 x 5 = 12,750
