1. Answer:

   perimeter =40

   2x+3x+5x =40

   10x=40

   x=40/10

   x=4 cm

   2x=8

   3x=12

   5x=20

2. Answer:

   The length of each sides of a triangle are 8cm, 12 cm , and 20 cm.

   Step-by-step explanation:

   Let the sides of the triangle be 2x,3x and 5x respectively.

   the perimeter of the triangle is 40cm

   => 2x+3x+5x = 40

   => 10x = 40

   => x = 40/10

   => x = 4

   Now,Putting value of x in each

   1st angle = 2x

   => 2×4

   => 8 cm

   2nd angle = 3x

   => 3×4

   => 12 cm

   3rd angle = 5x

   => 5×4

   => 20 cm

   Hence, the length of each sides of a triangle are 8cm, 12 cm , and 20 cm.
