Homework Help: Significant figures

  1. Feb 2, 2008 #1
    Hi everyone,

    Can someone please help me with this problem?

    The problem says:

    A parking lot is 115 ft by 200 ft. Find the area in m2

    My attempt:

    1m=3.281 ft

    So (115 ft)(1m/3.281ft)=35.1m

    (200ft)(1m/3.281ft)=70.0m

    A=(35.1m)(70.0m)
    A=2457m2=2.46X10^3m^2

    Thank you very much

    200/3.281 = 61.0, not 70.

    Also watch out for round-off errors.

    Thank you very much

    Does 2.14 X 10^3 m^2 look right?
