Answer:
64 inches
Step-by-step explanation:
We know the following:
- A chessboard is made of 64 white and black squares.
- The 64 squares are arranged in 8 rows and 8 columns.
- Each square is 2 inches thick.
From the first point, we see that a chessboard is a square. This means its length and width are equal.
This is also why the number of rows is equal to the number of columns.
It has been established that there are 8 rows (and 8 columns). Each row is made up of 8 squares.
Therefore, the length of 8 squares (a row) is:
L = 8 * 2 = 16 inches.
Hence, each row (and column) is 16 inches long.
Therefore, Perimeter will be:
P = 4L
P = 4 * 16
P = 64 inches
The perimeter of the chessboard is 64 inches.
