To find the length between two points using the Pythagorean theorem, we need to find the length of the legs of a right triangle with those points as its vertices.

The coordinates of the two points are (7,8) and (3,2). Using the distance formula, we can find the length of the legs:

Leg 1: (x1, y1) = (7, 8)
Leg 2: (x2, y2) = (3, 2)

Using the distance formula:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Let's plug in the values:
d = sqrt((3 - 7)^2 + (2 - 8)^2)
d = sqrt((-4)^2 + (-6)^2)
d = sqrt(16 + 36)
d = sqrt(52)

Now, we need to round our answer to the nearest hundredth:
d ≈ 7.21

Therefore, the length between the two points (7,8) and (3,2) is approximately 7.21 units.
