Through a rectangular field of sides `90 mxx60 m ,` 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 the roads is 3 m, find the total area covered by the two roads.

Through a rectangular field of length 90 m and breadth 60 m, two roads are constructed which are parallel to the sides and cut each other at right angles through the centre of the fields. If the width of each road is 3 m, find (i) the area covered by the roads. (ii) the cost of constructing the roads at the rate of Rs 110 per m^2

There is a rectangular field of size 94m xx32m .Three roads each of 2m width pass through the field such that two roads are parallel to the breadth of the field and the third is parallel to the length.Calculate: Area of the field covered by the three roads Area of the field not covered by the roads.

A rectangular lawn is 30m by 20m. It has two roads each 2m wide running in the middle of it one parallel to the length and the other parallel to the breadth.Find the area of the roads.

A grassy plot is 80m xx60m .two cross paths each 4m wide are constructed at right angles through the centre of the field,such that each path is parallel to one of the sides of the rectangles.Find the total area used path.Also, find the cost of gravelling them at Rs.5 per square metre.(fig.11)

A rectangular field is 50 m by 40 m. It has two roads through its centre, running parallel toits sides. The width of the longer and the shorter roads are 2 m and 2.5-m-respectivelyFind the area of the roads and the area of the remaining portion of the field.

The central park of the city is 40 metres long and 30 metres wide. The mayor wants to construct two roads of equal width in the park such that the roads intersect each other at right angles and the diagonals of the park are also the diagonals of the small square formed at the intersection of the two roads. Further, the mayor wants that the area of the two roads to be equal to the remaining area of the park. What should be the width of the roads?

A rectangular field is 50m by 40m. It has two roads through its centre,running parallel to its sides.The widths of the longer and shorter roads are 1.8m and 2.5m respectively.Find the area of the roads and the area of the remaining portion of the field.
