Question

What is the least number of square tiles of 1.2m each side required to pave the floor of a hall is 4.8 x 3.6?

Answer 1

Step-by-step explanation:

$area \: of \: floor = 4.8 \times 3.6 = 17.28 \: {m}^{2} \\ side \: of \: tile = 1.2 \: m \\ area \: of \: square \: tile = \: 1.2 \times 1.2 = 1.44 \: {m}^{2} \\ number \: of \: tiles \: required \: = \frac{area \: of \: floor}{area \: of \: one \: tile} \\ = \frac{17.28 \: {m}^{2} }{1.44 \: {m}^{2} } \\ = 12 \: tiles$
