Remaining yard area = Rectangular yard area- circular fountain area
Rectangular area = LxW
where
L= 19x
W= 14x
substitute the variables
= 14x x 19 x
= 266 x^2
circular fountain area = pi r^2
where r = 6x
subsitute the variable
= 36pi x^2
remaining yard area = 266x^2-36pix^2
= 2x^2(133-18pie)
The answer would be letter D. 2x^2(133-18pie)
