Through a rectangular field alens 90 metre and breadth 62 Road farm tractor which are parallel to the side and cut each other at right angle through the centre of the field if the width of the East Road is 3 metre find the area covered by the road the cost of constructing the road circle rate of rupees 110 per metre square

The area covered by the two roads is 441m²

Explanation:

I will rewrite the question editing the typos and completing the missing parts for better understanding:

Through a rectangular field of length 90m and breadth 60m, two roads are constructed which are parallel to the sides and cut each other at right angles through the centre of the field. if the width of each road is 3m, find the area covered by the roads.

The area covered by the roads is the area of the two roads less the common (intersection) area.

1. Area of the road that runs parallel to the breadth of 60m.

Area = length × width = 60m × 3m = 180m²

2. Area of the road that runs paralled to the length of 90m.

Area = length × width = 90m × 3m = 270m²

3. Area of the intersection of the two roads.

The intersection is a square of 3m of sidelength.

Area = (side length)² = (3m)² = 9m²

4. Area covered by the two roads.

180m² + 270m² - 9m² = 441m²
