Let
x------> the first even integer
x+2---->the second even integer
x+3---->the third even integer
we know that
-----> equation that represent the situation
solve for x
Combine like terms in the left side


therefore
<u>the answer is the option B</u>

The answer is 2.5 just set it up and cross multiply then divide
perimeter = sum of all sides
27 = 9+7.8+x
x (third side) = 10.2
