Find the area: you can split the figure into two rectangles.
The rectangles will be 7*20 and 7*11. The areas of those are <em>140 cm² and 77 cm²</em>. Add those up, and you get 217 cm².
Find the surface area: you can also split the net (the figure's surface area represented in a two-dimensional form) into two congruent triangles and three congruent rectangles. the triangles' area is <em>2(1/2*10*8) = 80 cm²</em>. The rectangles' area is <em>3(18*8) = 432 cm²</em>. Those totaled is 512 cm².

Answer:
Step-by-step explanation:
Find the total number of people
Total = those voting + those not voting
Total = 42 + 58

Answer:
Step-by-step explanation:
Ascending order: 17,22,22,26,39,41,47
Mode = 22
Median:
No. of terms = 7
Therefor, Median= (n+1)/2 th term = 8/2 = 4th term
Median = 26
Mean:
Mean = sum of the data/No. of data
-15. It would basically be -3 multiplied by 5 To get the answer.
