Answer:

Opposite sides are equal, which means that the given lengths are doubled and that'll have to equal a total of 82.

(2n) + (2n) + (4n + 5) + (4n + 5) = 82

Combine like terms;

4n + 8n + 10 = 82

12n + 10 = 82

Get rid of constants:;

-10 -10

12n = 72

Isolate n by getting rid of it's coefficient;

/12 /12

n = 6
