Sides of triangle

Triangle has a circumference of 42 cm. Side a is two times shorter than side b, and side c is 2 cm longer than side a. Find the sizes of the sides of a triangle.

Final Answer:

a =  16 cm
b =  8 cm
c =  18 cm

Step-by-step explanation:

o=42 cm  a+b+c=o a=2b c = a+2  a+a/2+(a+2)=o a+a/2+(a+2)=42  5a=80  a=580=16  a=16=16 cm
b=a/2=16/2=8 cm
c=a+2=16+2=18 cm
