The correct value of the length of a side = 2¼ ft
Answer:
area of the whole mosaic = 182.25 ft²
Step-by-step explanation:
We are told it has a 6 x 6 array of different colour square tiles.
Which means it has 6 x 6 = 36 square tiles.
Area of square = L²
Where L is length of side
Now, since length of one tile is 2¼ ft long.
Thus, area of one square tile = (2¼)²
= 81/16 ft²
Since there are 36 tiles,
Thus ;
Total area ; 81/16 x 36 = 182.25 ft²
