Answer:
B.
Step-by-step explanation:
Check the picture I have provided for each letter assigned to a shape.
I noted every shape with letters.
A and C are squares and all 3 B's and E are rectangles.
Now we need to calculate the surface area of every shape in order to find out the area of the whole shape.
The surface area of A and C can be found by using the following formula: where s means side.
A = 16×16 = 256
C = 16×16 = 256
The surface area of B and E can be found by using the following formula: w×l where w = width and l = length.
A single B = 16×8 = 128
All 3 B's = 128×3 = 384
E = 16×8 = 128
The area of the main shape is = 256+256+384+128 = 1024 square cm.
