Answer:
see explanation
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the measure of a side of the square )
Here s = x + 2 and A = 7, thus
(x + 2)² = 7 ← expand left side using FOIL
x² + 4x + 4 = 7 ( subtract 4 from both sides )
x² + 4x = 3 ← as required
52.2 / 145 = .36, which equals 36 %
I believe that the answer is A. 251 in.
this is because the diameter is 80. And to fimd the area/circumference of a circle you need to multiply the diameter times pi (3.14).
Hope this helped!
