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
Answer:
£1049.70
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
