Find the cost ?

Question

The floor of a room is in the shape of a square of side 4.8 m . The floor is to be covered with square tiles of perimeter 1.2 m . Find the cost of covering the floor if each tile cost Rs 27 .

Answer 1

Square tile has perimeter of 1.2m.
Square tile has four equal sides which form the perimeter.

Thus, length of each side of square tile
= 1.2m / 4
= 0.3m

Number of tiles lying on each side of the floor
= 4.8m / 0.3m
= 16 tiles

Total number of tiles
= 16 * 16
= 256 tiles

Cost of covering floor
= Rs 27 * 256
= Rs 6912
