Question

A floor whose length and width is 50 m and 40 m respectively needs to be covered by rectangular tiles. The dimension of each tile is 1 m x 2 m. Find the total number of tiles that would be required to fully cover the floor.

​

Answer 1

1000

Explanation:

area of rectangle = width x length

Given:

• width of floor = 40 m
• length of floor = 50 m

⇒ area of floor = 40 x 50 = 2000 m²

Given:

• width of tile = 1 m
• length of tile = 2 m

⇒ area of tile = 1 x 2 = 2 m²

Number of tiles needed = area of floor ÷ area of one tile

= 2000 ÷ 2

= 1000

Answer 2

1000 tiles needed.

area of floor:

• length * width

• 50 * 40

• 2000 m²

area of each tile:

• length * width

• 1 * 2

• 2 m²

solve:

`\sf total \ number \ of \ tiles \ needed = (area \ of \ floor)/(area \ of \ each \ tile)`

`\sf total \ number \ of \ tiles \ needed = \frac{2000}2}`

`\sf total \ number \ of \ tiles \ needed = 1000`
