Answer:
The height and width of the interior tile = 3·x + 4 - 4 = 3·x and 2·x + 4 - 4= 2·x
Please see attached diagram
Step-by-step explanation:
The given parameters are;
The given rectangular floor tile with width = 3·x + 4 and height = 2·x + 4
Where, x is in centimetres
The interior tile maintains a height to width ration of 2:3
The dimension of the trim border = 2 cm
Therefore;
The relationship between the width and height of the interior and exterior tiles is given as follows
Width of exterior tile = Width of interior tile + 2 × The dimension of the trim border
Which gives;
Width of exterior tile = Width of interior tile + 2 × 2 = Width of interior tile + 4
Height of exterior tile = Height of interior tile + 2 × The dimension of the trim border
Height of exterior tile = Height of interior tile + 2 × 2 = Height of interior tile + 4
Where the interior tile maintains a height to width ration of 2:3, we have;
For a unit length x, The height and the width of the interior tiles are 2·x:3·x
Therefore, for a given height 2·x, the width will be 3·x
Given the width of the exterior tile = 3·x + 4
The height of the exterior tile will then be 2·x + 4 and the width of the exterior tile will be 3·x + 4
The sides ratio of the interior tiles remain 2·x:3·x = 2/3
