A chessboard has an area of 100 square inches What is its perimeter?

To find the perimeter of the chessboard, we need to know the dimensions of the board. Since the area is given as 100 square inches, we can find the side length by taking the square root of the area, which is 10 inches. The perimeter of a square is calculated by adding all four sides together, so for this chessboard, the perimeter would be 10 inches + 10 inches + 10 inches + 10 inches = 40 inches.
