Let's analyze the image. It contains three different tasks:

1. Thursday Task:

   • A rectangular shape with dimensions $6 \, \text{in}$ and $18 \, \text{in}$.
   • The goal is to calculate the area and perimeter of the rectangle.

2. Wednesday Task:

   • A word problem involving canned goods:
     • Third grade donated 98 cans.
     • First grade donated 207 cans.
     • The task is to find how many more cans were donated by the second grade than the third grade.

3. Tuesday Task:

   • A polygon with labeled and missing sides.
   • The goal is to calculate the missing side and then determine the perimeter.

Let's solve them step-by-step:

Thursday Task (Rectangle):

• Area: $\text{Area} = \text{Length} \times \text{Width} = 18 \, \text{in} \times 6 \, \text{in} = 108 \, \text{square inches (sq in)}.$

• Perimeter: $\text{Perimeter} = 2 \times (\text{Length} + \text{Width}) = 2 \times (18 \, \text{in} + 6 \, \text{in}) = 2 \times 24 \, \text{in} = 48 \, \text{in}.$

Wednesday Task (Canned Goods):

• More Cans: $\text{Difference} = \text{First Grade Donation} - \text{Third Grade Donation} = 207 - 98 = 109 \, \text{more cans}.$

Tuesday Task (Polygon):

• Missing Side: To find the missing side (bottom part), use the total horizontal lengths: $\text{Missing Side} = 21 \, \text{ft} - (13 \, \text{ft} + 8 \, \text{ft}) = 21 - 21 = 0 \, \text{ft}.$

• Perimeter: Add up all the sides: $\text{Perimeter} = 21 \, \text{ft} + 13 \, \text{ft} + 8 \, \text{ft} + 5 \, \text{ft} + 13 \, \text{ft} + 8 \, \text{ft} = 68 \, \text{ft}.$

Let me know if you'd like more details!

Here are 5 related questions to build on this:

1. What are the formulas for area and perimeter of different polygons?
2. How can you calculate the area of a composite shape?
3. How can real-world data (like cans donated) be modeled into equations?
4. What is the importance of units in geometry problems?
5. How can subtraction errors impact solving real-world problems?

Tip: Always double-check units and label them in your answers! This ensures clarity and accuracy in mathematical solutions.
