Sequential Exercise 5
Required, a program that will calculate the number of packs and cost of the tiles required to cover the non-shaded area.
Algorithm
TileCalculation
centimetres to metres:= 10000
number in pack:= 15
read room length
read room width
read shaded length
read shaded width
area to tile:= room length * room width - shaded length
* shaded width
read tile side
area of tile:= tile side* tile side/centimetres to metres
{convert tile area to sq mtres}
tiles required:= area to tile/area of tile {rounded
up}
packs required:= tiles required/number in pack {rounded
up}
read cost per pack {leave
generic}
cost of tiles:= packs required*cost per pack
write number of packs
write cost of tiles
End.
