No real equations to use here...
The Attempt at a Solution
What length is the wall?
20 cm x 5 = 100 cm= 1 m
What height is the wall?
20 cm x 10 = 200 cm= 2 m
What is the area of the wall?
50 tiles x 400 cm2 = 20 000 cm2
If he uses square tiles of 10 cm sides, how many tiles would he need?
1 m length / 10 cm tiles = 10 tiles
2 m height / 10 cm tiles = 20 tiles
20 tiles x 10 tiles = 200 tiles used
