Substitute the value of x = 2 to the equation:

Answer:
x = 15/4, - 4
Step-by-step explanation:
I'm not sure :p
Area of square = 10x10
= 100
area of circle = pi(r)^2
= pi (5)^2
=25pi
area of shaded = 100 -25pi
circumference of circle = 2pi (r)
= 2pi(5)
= 10pi
perimeters of shaded = 10pi + 10 + 10
= 10pi +20
