Question 1134826
A rectangle has a length of 12 meters less than 2 times its width.  If the area of the rectangle is 2574
square meters, find the length of the rectangle.


---- meters?
<pre>Let width be W
Then length = 2W - 12
We then get: W(2W - 12) = 2,574
{{{matrix(1,3, 2W^2 - 12W - "2,574", "=", 0)}}}
{{{matrix(1,3, 2(W^2 - 6W - "1,287"), "=", 2(0))}}} ------ Factoring out GCF, 2
{{{matrix(1,3, W^2 - 6W - "1,287", "=", 0)}}}
Factors of 1,287 that sum to - 6 are - 39 and + 33
(W - 39)(W + 33) = 0
W, or width = 39 m
{{{highlight_green(matrix(1,6, Length, "=", 2(39) - 12, "=", 66, m))}}}
For your sake, IGNORE EVERYTHING that @ADDINGUP wrote, especially the part where he tells you that the width is - 33 m. RIDICULOUS!!!
