Length and breadth of a rectangular field are 130 m and 90 m, respectively. Inside it, a road of uniform width 15 m is left on all sides. In the remaining part, a park is made. What is the area of the road?

5500 m²
5800 m²
5600 m²
5700 m²

Correct answer: 5700 m²

Solution

The outer field area is $130\times 90=11700\,m^2$. Since the road is 15 m wide on all sides, the park dimensions are $130-30=100$ m and $90-30=60$ m, so park area is $100\times 60=6000\,m^2$. Therefore, road area = $11700-6000=5700\,m^2$.
