Question

a rectangular plot of land 200 m long and 150 m broad.It has two roads,each 4m wide running midway within it ,one parrallel to the length and the oter parallel to the breadth

Answer 1

Answer:

Answer

Given that the paths are 3m on each side and goes across to the center of the opposite side. So, basically we have on one side a rectangle of length 300m and width 3m whose area is A

1

=300×3=900m

2

and on another side a rectangle of length 50m and width 3m whose area is A

2

=50×3=150m

2

One important note, the area of the central part has been included twice, so it has to be subtracted from the total area covered by the path.

∴ Total area =900+150−(3×3)

=1050−9

=1041m

2

The cost of paving the road at Rs.50 per square meter is =Rs.1041×50

=Rs.52050

Hence, the answer is Rs.52050.
