Each square on Olivia's chessboard is 11 square centimeters. A chessboard has 8 square on each side. To the nearest tenth, what is the width of Olivia's chessboard?

the chessboard is about 26.4 centimeters long. to find the answer you need to know the length of one side of a square, which is about 3.3 centimeters, because the area is 11, so the square root of 11 is about 3.3 centimeters. there are 8 squares, so you have to multiply 8 times 3.3 which equals 26.4.
