उत्तर
Given: A rectangular field 250 m by 250 m with two roads, each 5 m wide, drawn through the middle one parallel to the length and the other parallel to the breadth.
Step-wise calculation:
1. Area of the vertical road
= length × width
= 250 × 5
= 1250 m2
2. Area of the horizontal road
= breadth × width
= 250 × 5
= 1250 m2
3. The two roads overlap in a square of side 5 m; overlap area
= 5 × 5
= 25 m2
4. Total area of the roads
= 1250 + 1250 – 25
= 2475 m2
The area of the roads is 2475 m2.
