Robbie draws a sqaure with an area of 856 square inches. what is the approximate length in inches of one side of the square

29.26 inches. Since the object Robbie drew is a square, we know that all 4 sides are the same length and the area of the square is L^2, where L is the length of one side. So A = L^2 856 in^2 = L^2 sqrt (856 in^2) = l&2 29.26 in = L So the length of one side is approximately 29.26 inches.
