	Actual measurement	Scale drawing measurement
Length of the room	$3.6 \mathrm{m}$	$6.5 \mathrm{cm}$
Width of the room	$3.3 \mathrm{m}$	$5.5 \mathrm{cm}$
Length of the bed	$1.5 \mathrm{m}$	$2.5 \mathrm{cm}$

Which one of the measurement is incorrect? Give reasons for your answer.

The diagram is a map showing two towns $\mathrm{A}$ and $\mathrm{B}$. This map is drawn to a scale of $1 \mathrm{cm}$ represents $2 \mathrm{km}$. $\mathrm{B}$ is due west of $\mathrm{A}$.

How far is $\mathrm{A}$ from $\mathrm{B}$ in real life?

The diagram is a map showing two towns $\mathrm{A}$ and $\mathrm{B}$. This map is drawn to a scale of $1 \mathrm{cm}$ represents $2 \mathrm{km}$. $\mathrm{B}$ is due west of $\mathrm{A}$.

Town $\mathrm{C}$ is on a bearing of $070°$ from $\mathrm{A}$ and $290°$ from $\mathrm{B}$. Mark the position of $\mathrm{C}$ onto your scale drawing.

Draw a line $PQ, 7 cm$ long on your page with space above and below it. $R is 4 cm$ from $P \& 5 cm$ from $Q$. Construct accurately all the possibles of $R$ on your diagram.

Draw a square, $ABCD$, of side $6 cm$ on your page. Construct accurately the locus of all points exactly $6 cm$ from $A$ which lies inside the square.
