Question from Jimi, a parent:

The area of a rectangular wall of a barn is 110 square feet. It's length is 12 feet longer than twice its width. Find the length and width of the wall of the barn.

Hi Jimi,

The area of a rectangle is the length times the width. Suppose the width is $w$ feet. What is twice the width? What is 12 feet more than twice the width? If you multiply this number by the width you get the area which is 110 square feet. This gives you an equation in the unknown $w$. Solve for $w$.
