It's a geometric sequence.

It's the sum for term 4 through term 15.
Okay so first, area is length times width, so 1/4x*x would be first = 1/4(x^2)=64. Then area or x = 16 or -16
perimeter would be width times two plus length times two. I recommend using math papa to calculate these numbers.
The answer is 6 degrees below the high.
89+6=95
95-12=83
