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.
