Thessa's Math Question

23. A rectangular floor that measures 3m by 2m is covered by 384 square tiles. determine the side lengths of each tile, in centimetres. State any assumptions you make.

First I converted M to CM.

3Mx100= 300cm

2Mx100= 200cm

Then I got the new area in cm. 300x200= 60 000 cm²

Then I divided the new area by the number of tiles.

60 000 ÷ 384 = 156. 25 cm

156.25cm² is the area of one tile.

Then I found the square root of that area to give me a side length.

√156.25 = 12.5 cm

*12.5 cm is the side lengths for each tile*
