You can put this solution on YOUR website! A football field has a perimeter of 310 yd and an area of 4950 yd square. What are the dimensions of the field?
------------------
2(L+W) = 310
L*W = 4950
------
L = 155-W
-------
(155-W)W = 4950
-W^2 + 155W - 4950 = 0
----
W^2 - 155W + 4950 = 0
-----
(W-110)(W-45) = 0
------
Usable solution::
Width = 110 yrd
Length = 155-W = 45 yrd
