PLEASE HELP ME WITH THIS ITS TO FIND THE SURFACE AREA

Answer:
21.45 m²
Step-by-step explanation:
Area of the smaller triangles =
1/2(1.7 * 3.5) * 2
1.7 * 3.5 = 5.95
Area of the bigger triangles =
1/2(3.1 * 3.3) * 2
3.1 * 3.3 = 10.23
Area of the rectangle on the bottom =
1.7 * 3.1 = 5.27
Total area =
5.95 + 10.23 + 5.27 = 21.45
