Working out above
Answer: 32.5sq in I believe
I multiplied all the sides (ex 0.5x2.5x2) and did that with all the other sides


This is a way to factoring trinomials (there exist different equivalent methods).
Multiply the trinomial but the term accompanying
. This is the second line. Then, you could take the square of the
, ant try to create a factor () () that will correspond to the expression in the second line. That is, we want 
In ? we put the corresponding numbers that, if we multiply them we will obtain 42, and if we add them we will obtain 13. This numbers are 6 and 7. Then, we have 
The last step is divide by the number that we multipy in the first step.
You have to find the common denominator which is 4 and multiply 26 by 4 which equals 104 add 3 which is 107 and divide by 4
Answer:107/4
