I think the answer is C because if you plug in the solution (4,2) in both the equation, none of the equation will be true. This will tell you that the solution is incorrect.
Hope this helped!

riadik2000 [5.3K]

Radius = 15
side = 6.215

a^2 = 15^2 - 6.215^2
a = 13.65

Area = a × p
Area = 13.65 × 99.44
Area = 1357.356
