The perimeter is the total measurement of all the sides together.
P = 82
Perimeter is side + side + side and so on.
So here is what we have.
15.4 + 16.2 + 28.7 + d = 82
Add up what you have now
60.3 + d = 82
Subtract 60.3 from both sides to get D
d = 82 - 60.3
d = 21.7
Answer:
=5803.28$ and 1760.99 $
Step-by-step explanation:
Given that Emile Zola, a senior Manager for Timber eye industries in California got a merit raise of 7.25% and cost of living 2.2%
Total increase in percent = 
After rise Emile salary is 87609.50 $
Let Emile salary -- 100
RIse -- 9.45
Salary after rise -- 109.45
THus we get if 109.45 is raised salary then merit increase =7.25
Hence for 87609.50, merit increase =
=5803.28$
Similarly we have cost of living increase=
= 
5 and 1 you multiple 5*1 to get 5 and add 5+1 to get 6
-1+1=0. So your answer is -1 and 1
