Answer 1

Its asking you for the surface area and equals 26

Answer 2

Well, you need to find the area of each shape (triangles and square). So  first you find the area of any triangle you see (the formula is 1/2 x base (3) x the height (5)). You then get 7.5. Multiply that with 4, because there are 4 triangles. you would get 30. so the area for the triangles are 30, and now for the square. The square's formula is length x height. (3 x 3) Which equals 9. So the area of the square is 9. Now finally you need to add the 30 (triangles) and the 9 (square) and you get the grand total of 39!!
