Determine if Mrs. Baxter will have enough chairs in her class and give a reason for your answer.

• Front table: 3 chairs
• Table near mirror: 4 chairs
• Back table: 6 chairs
• Art table: 4 chairs Total chairs = $3 + 4 + 6 + 4 = 17$ chairs.

Mrs. Baxter has 18 students but only 17 chairs.
No, Mrs. Baxter will not have enough chairs for 18 students because there are only 17 chairs available in the classroom.

• "DOOR TO WORKROOM"
• "HALLWAY DOOR" There are 2 exits in this classroom.

Scale = $1 : 100$
Measurement on plan = $29 \text{ mm}$

Actual length = Plan measurement $\times$ Scale factor
Actual length = $29 \text{ mm} \times 100 = 2900 \text{ mm}$

Since $1 \text{ m} = 1000 \text{ mm}$:

The actual length of the front table is $\boxed{\text{2.9 m}}$.
