Question:

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?

 

Options:

4000

7000

9000

8000

Correct Answer:

8000

Explanation:

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
