Question

A chessboard is made of 64 small squares. Suppose a single square on a chessboard has an area of 9 square centimeters. How long is one side of the entire board?

PLEASE HELPPP​

Answer 1

`72cm`

watch the cm sign too

Explanation:

`area = s2`

I think you should find the square root in order to get the length of one side

`√(64)`

answer is 8, then you multiply 8 by 9 to get the length of one side of the board

`9 * 8`

`= 72cm`

that should be your final answer
