Question 862707

a rectangular garage that has an area of 198 ft, the length is 7 ft longer than the width, what is the length of the garage.?
<pre>
Let width's measurement be W
Then length = W + 7
Therefore, W(W + 7) = 198
{{{W^2 + 7W - 198 = 0}}}
Solve for W, or width, discarding the negative (< 0) value
Add 7 to the value of W, or width to determine value of length
You can do the check!! 

If you need a complete and detailed solution, let me know!!
