Answer:
3.2
Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (A(2,2) and (x₂, y₂ ) = B(5, 1)
d = [tex]\sqrt{(5-2)^2+(1-2)^2}[/tex]
= [tex]\sqrt{3^2+(-1)^2}[/tex]
= [tex]\sqrt{9+1}[/tex] = [tex]\sqrt{10}[/tex] ≈ 3.2 ( nearest tenth )
