Yes it is a geometric sequence and the common ratio is 2/3
The correct quadratic equation;
x2+7x-2=0
Working
Assuming the frame has a uniform thickness;
Then length of mirror and frame is 3+x and width 2+x
The area of mirror and frame area;
A=L*W
8=(3+x)(2+x)
8=(6+5x+x2)
Taking 8 to the Right hand side, we have:
x2+5x-2 =0

Answer:
254.34
Step-by-step explanation:
This is because A=C2
4π which is 18x18 divided 4x 3.14 which equals 254.34
