Answer:
A. 648
Step-by-step explanation:
The special shape has a length of 2.02 m (202 cm) and width of 1.22 m (122 cm).
Given a tile of 2 cm × 2 cm, and that a double row of tiles make a border.
For a single row border,
the number of tiles required for its length = 202 /2 = 101
the number of tiles required for its width = 122/2 = 61
For a single row border, the total number of tiles for the perimeter of the special shape = 2 (101 + 61)
= 324
The number of tiles for a single row border is 324.
The number of tiles required to make the double row of tiles border = 2 (324)
= 648
The number of tiles required to make the border is at least 648.
