Ben is tiling the floor in his bathroom. the area he is tiling is 4m x 2m. each tile is 400m x 400 mm. he has 45 tiles. is this enough ​

This is not enough.

The area ben needs to tile is 4m x 2m, which is 8m^2. Each tile is 400mm x 400mm, which when converted to meters (dividing by 1000) is 0.4m x 0.4m = 0.16m^2. Multiplying this by the number of tiles, 45, we get 0.16 x 45 = 7.2, which is less than 8 and therefore is not enough area to tile the bathroom.

The answer is 30 minutes to an hour

Ithink the answer is a.3: 1i hope this
