Answer:
1. 7
2. 97
Step-by-step explanation:
3 is the bottom length of the triangle and its the same for both sides so that leaves us with the square in the middle, since the bottom of the triangle is 3 and the top of the trapezoid is 10 we subtract 3 from 10 and get 7 and since a square has all identical sides we know the area of the square is 7 x 7 = 49 + 48 (which is the two triangles) = 97
