Answer 1

Given,

A floor of a building is to be paved with 210 tiles which tiles is in the shape of a parallelogram of height 4.2 cm and base 3 cm.

To find :-

Find the cost of paving the tiles at rupees 2.50 per square cm

Solution :-

Dimensions of parallelogram = 4.2 cm×3 cm

∴ Area of parallelogram = Base×Height

⇒ Area of parallelogram = 4.2×3

⇒ Area of parallelogram = 12.6 cm²

Now there are 210 tiles.

⇒ Area of 210 tiles = 12.6 * 210

⇒ Area of 210 tiles = 2646 cm²

Now rate given as Rs. 2.5/cm²

⇒ Cost of paving = Area * Rate

⇒ Cost of paving = 2646 * 2.5

⇒ Cost of paving = Rs. 6615

Therefore,

Therefore,Cost of paving the tiles = Rs. 6615
