JLMN is a square, so all its sides are equal.<br><br>&bull; MN = 14 cm (side of the square).<br>&bull; JL = 14 cm (side of the same square).<br>&bull; IL is the total length from I to L, spanning both the rectangle GHIJ and the square JLMN.<br>&emsp; From the figure, IL = IG + JL. With IG = 9 cm and JL = 14 cm, IL = 9 + 14 = 23 cm.<br><br>Final Answer: MN = 14 cm, JL = 14 cm, IL = 23 cm
