Complete Question

Halima wants to cover all of the wall with tiles. The tiles are squares with sides of length 20 cm. The tiles are sold in packs. There are 10 tiles in each pack. Each pack of tiles costs £34.99 Halima only has £1000. How much would it cost Halima to tile the whole wall?

Length of the wall = 3m

Width of the wall = 4m

£1049.70

Step-by-step explanation:

100cm = 1m

1 tile = 20cm

100cm÷ 20cm = 5

1m = 5 tiles

Width = 4m = 4 × 5 = 20 tiles

Length = 3m = 3 × 5 = 15 tiles

Total tiles needed = 20 tiles × 15 tiles = 300 tiles

Remember: 1 pack contains 10 tiles

10 tiles = 1 pack

300 tiles = 300/10= 30 packs

Note: 1pack costs £34.99

30 packs = 30 × £34.99= £1049.70

Halima needs £1049.70 to cover the wall with tiles
