You have to add the areas of the three rectangles.
A1 = 39*11 = 429 m²
A2 = (39-12)*7 = 27*7 = 189 m²
A3 = 10*6 = 60 m²
A = 429 + 189 + 60 = 678 m².
Hope this helps !

Inferring that they are the only three players, all of their votes equal to 100%. If Dev gets 10%, that leaves 90% for Joe & Holly. You are now looking for a number that , when doubled adds to 90%.
Using an equation: a+2a=90
Solve for a.
3a=90 a=90/3
Now we have 10%,30%, & 60%
