Answer:
Step-by-step explanation:
Familiarize yourself with perfect squares in the neighborhood of 140:
10^2 = 100
11^2 = 121
12^2 = 144
Note that 140 is much closer to the perfect square than it is to the perfect square 121. The value of √140 must lie closer to 12 than to 11.
Place a point on the number line about 3/4 of the way from 11 to 12.
