Too Fly 4 u, this is the solution:
Step 1: Let's calculate the area of the kitchen, as follows:
Area = Length * Width
Area = 14 * 8
Area = 112 ft²
Scale = 3 inches = 2 feet
Tiles = 1 inch * 1 inch
Step 2: Let's calculate the number of tiles for having the right scale for the length of the kitchen, this way using the Direct Rule of Three:
Inches Feet
3 2
x 14
________________
2x = 42
x = 21 (Dividing by 2 at both sides)
This means that using the scale, the length of the model is 21 inches.
In consequence, we need 21 tiles for having the length of 21 inches.
Step 3: Now, let's calculate the number of tiles for having the right scale for the width of the kitchen, again using the Direct Rule of Three:
Inches Feet
3 2
x 8
___________
2x = 24
x = 12 (Dividing by 2 at both sides)
This means that using the scale, the width of the model is 12 tiles.
In consequence, we need 12 tiles for having the width of 12 inches.
Step 4: For covering the floor, we need:
Total tiles = Tiles for length * Tiles for width
Total tiles = 21 * 12
Total tiles = 252
