Design Brief & Client Requirements
The Community Garden Club has hired you to design 5 rectangular vegetable beds on this grid. Each small square represents 1 square foot (1 ft × 1 ft). Draw and label each rectangular patch using a ruler, then shade or outline each crop bed clearly. Leave pathways between beds!
Planting Guidelines & Required Bed Dimensions
1 grid square = 1 foot × 1 foot
🥕 Carrots 3 rows of 6 3 ft × 6 ft
🍅 Tomatoes 2 rows of 8 2 ft × 8 ft
🥬 Crisp Lettuce 4 rows of 4 4 ft × 4 ft
🌽 Sweet Corn 5 rows of 3 5 ft × 3 ft
🎃 Big Pumpkins Your Choice Array Area = 24 sq ft
Garden Plot Blueprint Canvas (20 ft × 14 ft Total Area)
1 Grid Square = 1 sq ft Border = Fencing Edge
0 5 ft 10 ft 15 ft 20 ft 5 ft 10 ft 14 ft
Tip: Outline each bed neatly with colored pencil. Label with crop name and array dimensions (e.g., 3 × 6).
Architect Check: Did you ensure the beds do not overlap? Are the pumpkin dimensions equal to 24 sq ft? Continue to Page 2 for Calculations →

Comparing Planting Space vs. Fencing: Tomatoes and Crisp Lettuce
Look closely at the tomato bed and lettuce bed in your table. Both have an area of 16 square feet. Do both beds require the exact same amount of perimeter fence? Why or why not? Explain using your calculations.

Pumpkin Array Investigation: Multiple Rectangles for 24 Square Feet
A teammate wants to build a pumpkin bed with an area of 24 square feet, but they don't know which dimensions to use. List two different rectangular arrays with an area of 24 sq ft and calculate the fence perimeter for each.
Option A: Dimensions: ____ ft × ____ ft = 24 sq ft
Perimeter calculation:
Option B: Dimensions: ____ ft × ____ ft = 24 sq ft
Perimeter calculation:

Architect Synthesis: The Relationship Between Arrays, Area, and Perimeter
Complete the rule in your own words: To find the total planting area of any rectangular bed, I multiply ________________________ by ________________________. To find the fencing perimeter around the bed, I ____________________________________________________________________.

Gardener's Math Toolkit: Area vs. Perimeter
A
AREA = Planting Space Inside
Think of rows and columns: Area = Length × Width. Measured in square units (sq ft).
P
PERIMETER = Fence Around Outside
Add all 4 outer edges: Perimeter = L + W + L + W. Measured in linear units (ft).
