<PRE><B>Question 744996</B>
The length of a rectangle is 1cm. more than twice its height. If the area of the rectangle is 351 sq cm, what is the perimeter of the rectangle? 
----------------------------------
Let height be &quot;x&quot; cm.
Then length is 2x+1 cm
------
Area = length*height = x(2x+1) = 2x^2+x
-----
Equation:
2x^2 +x = 351
2x^2 + x -351 = 0
-----
(x-13)(2x+27) = 0
-----
height = x = 13 cm
length = 2x+1 = 27 cm
----
Perimeter = 2(height + length) = 2(40) = 80 cm
