Question

Given $\overline{AB}$$=7.2cm$ and $\overline{CD}$$=2.9cm$Construct a line segment whose length is equal to $\overline{AB}$$-$$2$$\overline{CD}$

Answer 1

Step-1: Draw a line segment $\overline{AB}$$=7.2cm$

Step-2: Draw another line segment $\overline{CD}$$=2.9cm$

Step-3: Find $\overline{AB}$$-$$2$$\overline{CD}$

$$\begin{gathered} 7.2-\left(2\times 2.9\right) \\ 7.2-5.8 \\ 1.4cm \end{gathered}$$

Step-4: Draw $\overline{AB}$$-$ $2$$\overline{CD}$

Hence, $\overline{AB}$$-$$2$ $\overline{CD}$ has been constructed.
