Answer:
The total surface area of the whole figure would be 91.4cm
Explanation:
First I multiplied 6 x 3 then multiplied the answer by 9 for the area of the rectangle in the middle witch was 81. Then I multiplied 5.2 by 2 and got 10.4 then I added 81 ans 10.4 and the total area was 91.4cm. Really hope this helps! :)
