A checkers board is eight squares long and eight squares wide. The area of each square is 14 cm². Estimate the perimeter of the checkers board to the nearest 10th of a centimeter.

Area of each square = 14 cm²

length of each square = √14 = 3.74166 cm

Since the checkers board is 8 squares x 8 squares, length of one side = 8 x length of one square = 8 x 3.74166 = 29.93328 cm

Perimeter of the checkers board = 4 x 29.93328 = 119.73312 cm = 120 cm
