The area of a rectangular wall of a barn is 144 square feet. Its length is 10 feet longer than the width. Find the length and width of the wall of the barn.
The width is __feet.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

Let l and w be length and width, respectively. Then:

l x w=144

l = w + 10

The area will be given as;-

w(w+10)=144

w²+10w-144=0

(w+18)(w-8)=0

w = 8 and -18 ignore -18.

Therefore the width of the rectangular wall is 8 feet.
