so we will first find out the surface to be elementary
area of floor + area of 4 walls
area of floor =20×15
area of 4 walls=(2×20×4)+(2×15×4)
20×15+(2×20×4)+(2×15×4)=300+160+120
so the total area that have to element =580m²
and the cost for this is 580×12=6960 R.S.
HOPE THIS WILL BE HELPFULL FOR YOU
