In the image provided, the problem is asking about the length of a swimming pool. The area of the swimming pool is given as 18 square meters (m²), and the width is 3 meters. You need to determine the length of the pool.

Solution:

The formula for the area $A$ of a rectangle is: $A = \text{Length} \times \text{Width}$ We are given:

• $A = 18 \, \text{m}^2$
• $\text{Width} = 3 \, \text{m}$

To find the length, we rearrange the formula: $\text{Length} = \frac{A}{\text{Width}} = \frac{18}{3} = 6 \, \text{m}$

Thus, the length of the swimming pool is 6 meters, corresponding to option B.

Would you like more details on this? Here are some related questions to explore:

1. How do you calculate the perimeter of a swimming pool given the length and width?
2. If the pool's width was doubled, how would that affect the area?
3. What would the length be if the area were 24 square meters with the same width?
4. How do you calculate the volume of a pool if given the depth?
5. Can you calculate the diagonal of the swimming pool using the length and width?

Tip: In area-related problems, always make sure to check if the dimensions are consistent with the units for area.
