Question

Find the number of tiles required to be put on a floor with dimensions $25m\times 20m$. Each tiles is a rhombus,with side $25cm$ and altitude $10cm$

Answer 1

Area of floor$=25\times 20m$

$=500㎡$

Area of each tile=area if each rhombus

$=25\times 25=625㎠$

No. of tiles required$=\frac{areaoffloor}{areaofeachtile}$

$=\frac{500\times {10}^4}{625}$

$=\frac{4}{5}\times 10\times 1000$

$=8000$
