Question

a rectangular field of size 550m×360m is having a 5m wide road running around it from outside. how many tiles measuring 2m×2m will be required to cover the road. also find the total cost of covering the road with the tiles costing rs 2500 per 100 tiles

Answer 1

Hello, here’s your answer

Area of the field = 550x360 = 198000

New length (by adding 5+5) = 560

New breath (by adding 5+5) = 370

New Area = 560x370 = 207200

Area of the road = New area - given area

=207200-198000

=9200

Now,

Area of the tile = 2x2 = 4

No. Of tiles required to cover the road = area of the road/are of the tile

=9200/4

=2300

Now,

Cost of 100 tiles = 2500

Cost of 1 tile = 25

Cost of 2300 tiles = 2300x25

= 57500

Cheers
