The circular base of a planter sits on a level lawn, and just touches two straight garden walls at points W and Y. The walls come together at point X, which is 15 inches from the center of the planter. What is the area of the base of the planter?
(1) Both points Y and W are 9 inches from the center of the planter
(2) Point W is 12 inches from point X
Show Spoilermy take
Went for A. Having a radius of 9 allows to calculate the size. Wrong answer though

D.
Stmt2 is sufficient too. Draw a line from X to center of circle O. Length is 15.
Also join center of circle to point W. triangle XOW forms right angel triangle with one base 12 and hypotenuse 15. We can find OW (the radius). hence we can find the area.
Also, please include OA under spoilers.
Thanks.
