Explanation:

Step1: Recall pressure formula

Pressure \( P \) is calculated by the formula \( P=\frac{F}{A} \), where \( F \) is force and \( A \) is area.

Step2: Substitute values

Given \( F = 450\) newtons and \( A = 2\) square meters. Substitute into the formula: \( P=\frac{450}{2}=225\) pascals.

Step3: Convert to kilopascals

Since \( 1\) kilopascal \( = 1000\) pascals, divide by \( 1000 \): \( 225\div1000 = 0.225\) kPa.

Answer:

C. 0.225 kPa
