Calculating the Number of Ceiling Tiles Needed

To calculate the number of ceiling tiles needed to cover the rectangular ceiling, we can use the following formula:

Number of tiles = (Ceiling area) / (Area of one tile)

The area of the ceiling can be calculated by multiplying the length and width of the ceiling. Given: - Length of the rectangular ceiling = 26 m - Width of the rectangular ceiling = 8 m - Length of one side of the square tile = 2 m

Calculation

The area of the ceiling = Length × Width The area of one tile = Side length × Side length

Substituting the given values: - Area of the ceiling = 26 m × 8 m - Area of one tile = 2 m × 2 m

Now, we can calculate the number of tiles needed using the formula mentioned above.

Result

Number of tiles = (26 m × 8 m) / (2 m × 2 m)

Number of tiles = (208 m²) / (4 m²)

Number of tiles = 52

So, 52 navesnykh plitok will be needed to cover the ceiling.
