nadya68 [22]

Answer:   2730 tiles (Approx)    

Step-by-step explanation:

Since, The side length of each side = 25

According to the question the shape of the tile is square.

Thus, the area of one tile = 25 × 25 = 625 cm^2

Also, we need to tile a kitchen measuring 102 ft. by 18 ft

Thus, the area of the room in which we have to tile =  102 × 18 = 1836 feet^2 = 1836×30.48 × 30.48 = 1705699.8144 cm^2

Thus, the total number of the tiles = the area of the room in which we have to tile / the area of one tile = \frac{1705699.8144}{625} = 2729.11970304

Since, we must take 2730 tiles to tile the kitchen.
