Hey there !!
Let the ratio be x.
=> perimeter of rectangle = 2( l + b ) .
=> 20 = 2( 3x + 2x ) .
=> 20 = 2 × 5x.
=> 20 = 10x .
=> x = 20/10 .
•°• x = 2.
°•° Length = 3x = 3 × 2 = 6cm.
°•° Breadth = 2x = 2 × 2 = 4cm.
▶ Method of construction :-
→ Draw a line AB of length 6 cm.
→ Make an angle of 90° at point A and B .
→ Draw an arc at point C and D such that = BC = AD = 4cm .
→ Now, join the line CD.
For figure, see the attachment.
✔✔ Hence, the figure so formed is rectangle of length 6cm and breadth 4 cm ✅✅ .
