Respuesta :

area of a triangle=bh/2, area of a square is side squared

a=7x4=28/2=14, and since there are 3 triangles multiply and get 42
 a=7x7=49
42+49=91

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 :)
