L^2+11 and if i am wrong please correct me
Answer by scott8148(6628)   (Show Source):
You can put this solution on YOUR website! using the first point, a=L*W ... 10=10*W ... W=1
L+W=11 ... W=11-L ... a=L(11-L) ... a=11L-L^2
this is a continuous function that describes the area of a rectangle with a fixed perimeter
... you can connect the points because each point on the graph represents some combination of L and W that gives a different area
L and W can have any positive values as long as they add to 11 ... the perimeter is 22
