Markuo's window store made a mosaic for the community center. The mosaic had a 7 × 7 array of different color square tiles. If each tile is 3 1 2 ft long, what is the area of the whole mosaic?

The correct value of the length of each square tile is 3½ feet long.

Total area of mosaic = 600.25 sq.ft

Step-by-step explanation:

We are told the length of each square tile = 3½ ft.

Area of square = L²

Where L is length of side.

Thus;

Area = 3½ × 3½

Area = 49/4 sq.ft

Now, an array of 7 x 7 means 7 rows and 7 columns

Thus, total number of square tiles = 7 x 7 = 49 tiles

So,

total area of whole mosaic = number of tiles × Area of 1 tile

Total area = 49 × 49/4 = 600.25 sq.ft
