Answer
Given: $AB= 7.5\ cm$ and $CD = 2.5\ cm$ Draw $AB$ and $CD$
Draw a line I and take a point $E$ on it. Now take a divider and open it such that the ends of both its arms are at $C$ and $D.$ Then, we lift the divider and place its end at $E$ on it and other end $(F)$ on the line $I$, as shown in the figure. Again, we lift the divider end $(G)$ on the I opposite to $C$. Again, lift the divider end $(G)$ on the line $I$ opposite to $C$. Again, lift the divider and place its one end at G and another end $( H )$ on the line $I$ , opposite to $E . EH$ is required line segment, whose length is equal to $3 C D$.
