Best ResponseYou've already chosen the best response.0h': 1 cm/min A': 2 cm^2/min. b'?: h=10 cm, A=100cm^2 A = bh/2 A' = b'h/2 + bh'/2 b' = (A'  bh'/2)(2/h)

Best ResponseYou've already chosen the best response.0b' = (A'  2Ah'/2h)(2/h) b' = (A'  Ah'/h)(2/h) b' = (2  100(1)/10) (2/10) b' = (2  10) (1/5) b' = 8/5 maybe?
