Explanation:

Step1: Recall the definition of squaring a number

Squaring a number means multiplying the number by itself. So, \(17^2\) is \(17\times17\).

Step2: Calculate \(17\times17\)

We can calculate \(17\times17\) as follows: \(17\times17=(10 + 7)\times(10 + 7)=10\times10+10\times7 + 7\times10+7\times7=100 + 70+70 + 49=100+140 + 49=240+49 = 289\). We also know that \(15^2 = 225\), so \(17^2\) is not 225.

Answer:

A. 289
