1. Answer:

   15 cm is the answer.

   Step-by-step explanation:

   Let breadth be x

   Let length be 2x

   B/Q 2(2x+x) =90

   2×3x=90

   3x=90/2

   3x=45

   x=45/3=15

   Therefore the length is 15 cm

2. Answer:

   breadth = 2X

   length =x

   perimeter = 2(l +b)

   [tex]2(x + 2x) = 90[/tex]

   [tex]2 \times 3x = 90[/tex]

   [tex]6x = 90[/tex]

   [tex]x = 90 \div 6[/tex]

   [tex]x = 15[/tex]
