See a solution process below:

Using the standard order of operation or PEDMAS, first, execute the subtraction operation within the Parenthesis:

$12.5 + 4 \times (11.2 - 2) \Rightarrow 12.5 + 4 \times 9.2$ $12.5 + 4 xx (color(red)(11.2) - color(red)(2)) => 12.5 + 4 xx 9.2$

Next, execute the Multiplication operation:

$12.5 + 4 \times 9.2 \Rightarrow 12.5 + 36.8$ $12.5 + color(red)(4) xx color(red)(9.2) => 12.5 + 36.8$

Now, execute the Addition operation:

$12.5 + 36.8 \Rightarrow 49.3$ $color(red)(12.5) + color(red)(36.8) => 49.3$
