Answer: 60 + 13 sqrt 10
the top part adds up to 10 and the bottom part is 13
so you get a 7-3-2 sqrt 10 triangle to the left
the area of that is 3 sqrt 10
the area of the leftmost rectangle is 5 * 2sqrt 10 which is 10 sqrt 10
the area of the big vertical rectangle is 5*12 which is 60
so you add them up
60 + 13 sqrt 10
It is in simplified form. You cannot add these together because they are different terms. EX: bc, b, and c. They don't correspond, so we can't add/subtract/multiply/divide.
