Answer:
172 m^2.
So you already have it on the correct answer.
Step-by-step explanation:
For you to find the surface area, you need to find out the areas of all the different colored sections.
There are 6 sections.
2 green, 2 purple, and 2 red.
Green section: (length x width) 7 x 8 = 56
Purple section: (length x width) 2 x 8 = 16
Red section: ( length x width) 7 x 2 = 14
Total: 56 + 16 +56 + 16 + 14 + 14 = 172 cm².
