Maybe a rectangle?
2L + 2 W =400 so L + w = 200 so L =200-w
L w = 9100
(200-w) w = 9100
w^2 -200 w + 9100 = 0
w = [ 200 +/- sqrt (40000 - 36400)] / 2
w = [ 200 +/- 60 ] / 2
w = 130 or 70
2L + 2 W =400 so L + w = 200 so L =200-w
L w = 9100
(200-w) w = 9100
w^2 -200 w + 9100 = 0
w = [ 200 +/- sqrt (40000 - 36400)] / 2
w = [ 200 +/- 60 ] / 2
w = 130 or 70

list all possible rational zeros for the given function f(x) = 5x^4+15x^3-7x^2x-10 = ?
