What is the length of side AB? Round your answer to the nearest tenth.

ELEN [110]

Answer:

AB ≈ 2.8 units

Step-by-step explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(1, 1) and (x₂, y₂ ) = B(3, 3)

AB = $\sqrt{(3-1)^2+(3-1)^2}$

= $\sqrt{2^2+2^2}$

= $\sqrt{4+4}$

= $\sqrt{8}$ ≈ 2.8 units ( to the nearest tenth )
