To find the length between the points (1,5) and (4,8), we can use the Pythagorean Theorem.
The formula is: c = √(a^2 + b^2), where c is the length of the hypotenuse (the distance between the points), and a and b are the lengths of the other two sides of the right triangle formed by the points. In this case, a is the difference in x-coordinates (4 - 1 = 3) and b is the difference in y-coordinates (8 - 5 = 3).
c = √(3^2 + 3^2)
c = √(9 + 9)
c = √18
Rounding to the nearest hundredth, the length between the points is approximately 4.24. So the correct answer is 4.24.
