Answer:
To solve for n you need to get it by itself
First you want to distribute your 2 through the (3n+14)
-2n+6n+28=-20 (2*3n+2*14= 6n+28)
Now you want to combine any like terms if possible
4n+28=-20 (-2n+6n=4n, both like terms)
Then you want to subtract -28 from both sides
4n=-48 (28-28=0, -20-28=-48)
Lastly you want to divide both sides by 4
n=-12 (4n/4=n, -48/4= -12)
the shorter sides are 4 inches and the longer sides are 21 inches long

Answer:
48m squared
Step-by-step explanation:
- cut the problem in half horizontally
you get two squares one square is 4 by 4 and the other 8 by 4
