Math Problem Statement

The coordinates of point L are (2, 0). The coordinates of point G are (4, 9). Determine the length of segment LG.

Solution

To solve for the distance between points L(2,0)L(2, 0) and G(4,9)G(4, 9), we use the distance formula:

d=(x2x1)2+(y2y1)2d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Here, the coordinates of LL are (x1,y1)=(2,0)(x_1, y_1) = (2, 0) and the coordinates of GG are (x2,y2)=(4,9)(x_2, y_2) = (4, 9).

Substituting the values into the formula:

d=(42)2+(90)2d = \sqrt{(4 - 2)^2 + (9 - 0)^2} d=(2)2+(9)2d = \sqrt{(2)^2 + (9)^2} d=4+81d = \sqrt{4 + 81} d=85d = \sqrt{85}

Therefore, the distance between points LL and GG is:

d9.22 metersd \approx 9.22 \text{ meters}
