Best ResponseYou've already chosen the best response.2\[400^2+900^2=c^2\] To simplify things, we're going to divide by 100 to get this \[4^2+9^2=c^2\] \[16+81=c^2\] \[97=c^2\] \[c=\sqrt{97}\] \[c \approx 9.849\] Since we divided this by 100, we have to multiply by 100, so the answer would be \[984.9 \] feet
