The only way I can figure this problem makes any sense

is that its intent is to demonstrate the effect of rounding.

For the minimum, use 5**.**5 in place of the 6, and 10**.**51 in place of the 11.

Minimum area is (5**.**5 km)(10**.**51 km) = 57**.**80 km^{2}

For the maximum, use 6**.**5 in place of the 6, and 11**.**49 in place of the 11.

Maximum area is (6**.**5 km)(11**.**49 km) = 74**.**68 km^{2}
