Question 983647
The perimeter of a rectangular building is 170 meters. The area is 
1,624 square meters. What are the dimensions of the building?
------------
L+W = 85
L*W = 1624
------
Substitute for "W" and solve for "L"::
W = 85-L
-----
L(85-L) = 1624
----
L^2 - 85L + 1624 = 0
----
Positive solution:
Length = 29 meters ; Width = 85-29 = 56 meters
