x - width x+6 - length
x ( x + 6 ) = 55 x 2 + 6 x − 55 = 0 x 2 + 11 x − 5 x − 55 = 0 x ( x + 11 ) − 5 ( x + 11 ) = 0 ( x − 5 ) ( x + 11 ) = 0 x = 5 ∨ x = − 11
x=5 feet x+6=11 feet
The dimensions of the barn wall are found by setting up and solving a quadratic equation involving its area and the relationship between its length and width. Discarding the nonsensical negative solution, we find that the **width **of the wall is 5 feet and the length is 11 feet. ;
The width of the barn wall is 5 feet and the length is 11 feet. This was determined by setting up and solving a quadratic equation based on the area and the length being 6 feet longer than the width. The quadratic equation narrowed the possible solutions to the valid dimension of the wall.
