HELP HELP 5.) A gardener wants to divide a square piece of lawn in half diagonally. what is the length of the diagonal side of the square is 8 fr. leave your answer in simplest radical form.

diagonal ^2 = 8^2 + 8^2diagonal ^2 = 64 + 64diagonal ^2 = 128diagonal ^2 = 64 * 2diagonal ^2 = 8 * sq root (2)****************************************************Diagonal of a square = SqrRoot (2 * side^2)Diagonal = SqrRoot (2 * 8^2)Diagonal = SqrRoot (128)SqrRoot (128) = SqrRoot (2 * 64) = SqrRoot (2) * 8DIAGONAL = SqrRoot (2) * 8
