find values for r and t such that the inequality r < S < t best describes s, the length of the third sides of a triangle for which the lengths of the other two sides are given.

11. 2 and 4

thanks for the help !

This could be a rt. triangle:

s^2 + r^2 = t^2,
s^2 + 4^2 =(11.2)^2,
s^2 + 16 = 125.44,
s^2 = 125.44 - 16,
s^2 = 109.44,
s = sqrt(109.44) = 10.5.

r < s < t,
4 < 10.5 < 11.2.
