We can use the formula for the area of a triangle:

(area) = 1/2 (base)(height)

To find the base and height, we can use the Pythagorean theorem:

(base)^2 + (height)^2 = (hypotenuse)^2

In this case, we can use 18 m as the hypotenuse.

First, we can find the length of segment PQ:

PQ^2 = 18^2 - 8^2 = 256

PQ = 16

Now we can use PQ as the base and find the height:

(height)^2 = 18^2 - 16^2 = 68

height ≈ 8.25

Then we can find the area:

(area) = 1/2 (16)(8.25) ≈ 66.0

Rounding to the nearest tenth, the area of triangle APQR is 66.0 m².

Answer: O 65.3 m²
