Given:

The perimeter of a backyard basketball court with four sides is 90 feet.

Two sides of the court are each 20 feet long.

One side of the court is 25 feet long.

To find:

The missing side length of the basketball court.

Solution:

Let x be the missing side length.

The three given sides of the basketball court are 20 feet, 20 feet, 25 feet.

We know that the perimeter is the sum of all sides.

$Perimeter=x+20+20+25$

$Perimeter=x+65$

The perimeter of a backyard basketball court with four sides is 90 feet.

$x+65=90$

$x=90-65$

$x=25$

Therefore, the missing side length is 25 feet and the correct option is B.
