Gotcha.
So to find the triangles it's going to be 7*4 which is 28 then divide it by 2.
This is 14, so the area of one half, of the bigger triangle is 14, then add 14 6 times or just times it by 6. Which is 84.
Now find the area of the square which is 7*7 and that's 49. So add 84 and 49 and that's your answer.
Which means it's 133 :)
