a 16 by 18 foot rectangular section will be covered by square tiles that measured 2 feet on each side if the tiles are not cut how many of them will be needed to cover the section of the wall

No. of tiles on each side=16/2 and 18/2 i.e. 8 and 9.

Total tiles reqd==8*9=72.
Or else,
Area to be covered=16*18=288sqft
Area of each tile=2*2=4sqft,
hence no. of tiles=288/4=72.

To find the number of square tiles needed to cover the 16 by 18 foot rectangular section, we need to calculate the total area of the section and divide it by the area of each tile.

First, let's calculate the area of the rectangular section using the formula: Area = length × width.
Area of the rectangular section = 16 feet × 18 feet = 288 square feet.

Next, let's calculate the area of each tile using the formula: Area = side length × side length.
Area of each tile = 2 feet × 2 feet = 4 square feet.

Finally, divide the total area of the rectangular section by the area of each tile to get the total number of tiles needed:
Number of tiles = Total area / Area of each tile = 288 square feet / 4 square feet = 72 tiles.

Therefore, you will need 72 square tiles to cover the 16 by 18 foot rectangular section.

To find out how many square tiles are needed to cover the 16 by 18 foot rectangular section, we need to calculate the total area of the section and then divide it by the area of each tile.

The area of the section is calculated by multiplying the length (16 feet) by the width (18 feet):
16 feet * 18 feet = 288 square feet

The area of each tile is calculated by multiplying the length of one side (2 feet) by itself:
2 feet * 2 feet = 4 square feet

Now we can divide the total area of the section by the area of each tile to find the number of tiles needed:
288 square feet / 4 square feet = 72 tiles

Therefore, you would need 72 square tiles to cover the 16 by 18 foot rectangular section without cutting any of the tiles.
