Answer:

Side a = 20.8                            

Side b = 20.5

Side c = 30

Side d = 2

Side e = 12.6

Step-by-step explanation:

We need to know what X is here is the equation:

3.2a+8+12.6+[tex]\frac{1}{2}a[/tex]+5(a+2)+(6a-3.5)=85.9

After doing the math you get a=4.

Apply this to each side and get the answer.

Side a = 20.8                            

Side b = 20.5

Side c = 30

Side d = 2

Side e = 12.6

Check

20.8+20.5+30+2+12.6=85.9
