UVWX is a square, so all its sides are equal.<br><br>&bull; UV is a side of square UVWX. From the figure, UV = 3 cm.<br>&bull; TV is the total length from T to V. T lies on rectangle RSTU and V lies on square UVWX.<br>&emsp; TV = TU + UV. With TU = 3 cm and UV = 3 cm, TV = 3 + 3 = 6 cm.<br><br>Final Answer: UV = 3 cm, TV = 6 cm
