Answer:
RS ≈ 5.83 units
Step-by-step explanation:
Calculate RS using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = R(- 3, 1) and (x₂, y₂ ) = S(2, 4)
RS = ![\sqrt{(2+3)^2+(4-1)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%282%2B3%29%5E2%2B%284-1%29%5E2%7D)
= ![\sqrt{5^2+3^2}](https://tex.z-dn.net/?f=%5Csqrt%7B5%5E2%2B3%5E2%7D)
= ![\sqrt{25+9}](https://tex.z-dn.net/?f=%5Csqrt%7B25%2B9%7D)

≈ 5.83 ( to 3 significant figures )
