Length of a class room is two times its height and its breadth is `1 1/2` times its height. The cost of white-washing the walls at the rate of `R s .1.60\ p e r\ m^2` is `R s .179.20.` Find the cost of tiling the floor at the rate of `R s .6.75\ p e r\ m^2`

Explanation

given that,

`l=2h`

`b=(3/2)h`

The cost of white-washing the walls`=Rs 179.20`

rate`= Rs 1.60`

so total area of wall`=179.20/1.60`

`=112m^2`

`2h(l+b)=112`
