The first equation is 
(Equation 1)
The second equation is
(Equation 2)
Putting the value of x from equation 1 in equation 2.
we get,


by simplifying the given equation,


Using discriminant formula,


Now the formula for solution 'x' of quadratic equation is given by:


Hence, these are the required solutions.

The solution to the given question is here , sry for having bad handwriting but its solved . If u don’t understand the solution then u can ask me again
Because the diameter is 47 cm
so the radius is 2x
r = 94 cm
A = πr² / 2
A = (3.14) (94)² / 2
A = 13872.52 cm²
