Step-by-step explanation:
Length = 18 3/4 feet = 75/4 feet = 225 inches
Size of each tile = 1 1/2 feet = 18 inches
Number of tiles needed
= length/size
= 225/18
= 25/2
=12.5 tiles
Natasha needs 12 and a half tiles.
She needs 12 + a half tiles in total.
Given that:
Length of one side of bathroom = [tex]18\dfrac{3}{4} = \dfrac{75}{4}[/tex] feet.
Length of each tile = [tex]1\dfrac{1}{2} = \dfrac{3}{2}[/tex] feet.
To find:
Number of tiles she need for this section.
Calculations:
We use division to find how many tiles would she need:
[tex]\text{Number of tiles} = \dfrac{\text{Total length of side}}{\text{Length of tile}}\\\\\text{Number of tiles} = \dfrac{\dfrac{75}{4}}{\dfrac{3}{2}}\\\\\text{Number of tiles} = \dfrac{75 \times 2}{4 \times 3}\\\\\text{Number of tiles} = \dfrac{25}{2} = 12.5\\\\[/tex]
Thus, in total, she would need 12 + 0.5 = 12 tiles and a half of a tile.
