To find the distance the car needs to travel to return to point P from point R, we first need to determine the distance between points P and R.
The triangle formed by points P, Q, and R has sides of 3 meters (PQ) and 4 meters (QR). We can use the Pythagorean theorem to find the length of side PR if we assume that the triangle is a right triangle. The formula is:
\[ c^2 = a^2 + b^2 \]
where \( c \) is the hypotenuse (PR) and \( a \) and \( b \)
