I'm not sure you are asking the right question? it tells you what the radius is right there. What is the question asking
Answer:
That is a right angles triangle which means to get the area: multiply the base(14.1)to be the height (9.8) divided by 2.
Formula : half the base times the height given. Your answer is to be squared and don't forget the correct unit.
To combine these terms you would add up the a's and b's.
4a+b+a is the same as 4a+a+b. Anything without a constant in front has a value of 1. You have 4a's and you need to add another a. That equals 5a's. The b is left alone since you can only add like variables.
The answer would be C) 5a +b
