1. the area of a square game board is 144 sq. in. what's the length of the sides of the board?

Area is leinght times hieght and since it is a square board, that means all sides are the same so we need the square root of 144 which is twelve.  The lenght of one side is 12 and the entire perimeder 48

It is 12 because a square has four equal sides and 144 divided by 4 is 12 so the answer is 12

Iagree that is the answer to the question
