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.

Feel free to let me know if you need more help. :)

It’s 172m^2
Because the rectangular middle piece is 18 by 8 which equals 144 then you had the smaller pieces with are both 14 and when you had all three you get 172
