[x] 2x^2 (21 – 2pi) c. 42x^2 – 2pix^2 d. 38pix^2,

Step

Find the area of the rectangular yard

the area of the rectangular yard is equal to

where

L is the length side of the rectangle

W is width side of the rectangle

in this problem we have

Step

Find the area of a circular fountain

we know that

the area of a circle is equal to

where

r is the radius of the circle

in this problem we have

substitute

Step

Find area of the remaining yard

Subtract the area of a circular fountain from the area of the rectangular yard

therefore

the answer is the option B
