Step-by-step explanation:
We have:
(1) two trapezoids with bases b₁ = 7cm and b₂ = 5cm and the height h = 4cm
(2) three rectangles 3 cm × 7 cm, 3 cm × 4 cm and 3 cm × 5 cm.
The formula of an area of a trapezoid:

Substitute:

Calculate the areas of the rectangles:

The Surface Area:

Answer:
Step-by-step explanation:
A = -2.2
E.
( -2.1 ) + ( - 0.1 )
( -2.1 ) - 0.1. <—— over there, you will see that + is gone and the - has moved down, I done that because + plus with - equals to -.
-2.1
-0.1
———-
-2.2
The answer is 19
