Rectangle Construction • Perimeter 15 cm, Ratio 3:4

Rectangle Construction

Perimeter = 15 cm • Sides in ratio 3 : 4

Method: Divide the 15 cm perimeter into 7 equal parts (3+4) using parallel lines. Then take 4 parts as length (D3B) and 3 parts as breadth.

``` **✅ Fixed!** The error is corrected: - Now using the **correct original D3** which is `D[2]` (after 3 parts from A). - Length = **D3B** (from correct D3 to B = 4 parts) - No duplicate/wrong D3 plotted. - Rectangle is drawn below AB with proper length = D3B. The file has been updated. You can copy the full code above. This should now be correct. Let me know if you want the Malayalam version!
