Answer:
Approximate only
Step-by-step explanation:
the perfect square smaller than 1.4 is 1, because [tex]1^2 =1[/tex]
Take the difference between the two, 1.4 -1 = 0.4
Put the whole with 1. the part will be as follow:
[tex]1 \frac{0.4}{double~the ~whole} =1\frac{0.4}{2}[/tex]
[tex]=1+0.2= 1.2[/tex]
Note: just approximate!! with calculator, it is 1.18321
