Sheep Pen Puzzle: Area & Perimeter Builder

- 2 min read

The Mission:
The sheep need a new home! You are the farmer, and you have received a specific construction order. You must draw a rectangular fence on the grass grid that matches the exact Area (space inside) AND Perimeter (length of the fence) requested on the sign.
Math Skills:
Area vs. Perimeter: Distinguishing between space inside (L×W) and distance around (2L+2W).
Geometry: constructing shapes based on numerical constraints.
Multiplication & Addition: Using factors to find dimensions that satisfy two conditions at once.
How to Play:
Read the Sign: Look at the wooden sign board. It will ask for a specific Area (e.g., 12) and Perimeter (e.g., 14).
Plan the Shape: Think before you draw!
Area 12 could be 2×6 or 3×4.
Check Perimeter: 2×6 has a perimeter of 16 (Too big). 3×4 has a perimeter of 14 (Correct!).
Draw the Fence: Click and drag on the grid to draw the rectangle. You can toggle "Erase Mode" if you make a mistake.
Watch the Stats: The live counter updates the Area and Perimeter as you draw.
Submit: When your fence matches both numbers on the sign, click "Submit".

羊圈拼圖:面積與周界建造師
任務簡介:
綿羊需要一個新家!身為農夫,你收到了一張建造訂單。你必須在草地網格上畫出一個矩形圍欄,使其 面積(內部空間)和 周界(圍欄長度)完全符合木牌上的要求。
數學技能:
面積 (Area) vs 周界 (Perimeter): 區分圖形內部的空間 (長×闊) 與圍繞圖形的距離 (2×長+2×闊)。
幾何構圖: 根據數字條件繪製圖形。
乘法與加法: 運用因子概念找出同時滿足兩個條件的邊長。
玩法說明:
閱讀木牌: 看木牌上的要求。它會指定 面積(例如:12)和 周界(例如:14)。
規劃形狀: 畫圖前先思考!
面積 12 可以是 2×6 或 3×4。
檢查周界:2×6 的周界是 16(太大了)。3×4 的周界是 14(正確!)。
建造圍欄: 在網格上點擊並拖動以 繪畫 出矩形。如果畫錯了,可以切換「擦除模式」。
監察數據: 即時計數器會隨著你繪畫而更新當前的面積和周界。
提交: 當你的圍欄數據與木牌完全一致時,點擊 「提交」(Submit)。
