GIVEN↴

total no.of tiles=2000

Area Of 1 Tile=1/2×d1×d2

=1/2×40×25

=500cm.sq

area of 2000 tiles=500×2000

=10,00,000cm.sq

10,00,000cm.sq = 1000m.sq [100 cm=1m]

cost of polishing per m.sq=5Rs

cost of polishing 1000m.sq=1000×5

=5000Rs.

Answer 2

☘️ Answer ☘️

Solution ↓

total no.of tiles= 2000

Area Of 1 Tile = 1/2 × d1 ×d2

=1/2×40×25

=500cm.sq

area of 2000 tiles = 500×2000

=10,00,000cm.sq

10,00,000cm.sq = 1000m.sq [100 cm=1m]

cost of polishing per m.sq= Rs. 5

cost of polishing 1000m.sq = 1000×5

= Rs. 5000
