Answer 2

We know that

$Perimeter \: of \: square = 4 \times side \\ \\ 60 = 4 \times side \\ \\ \frac{60}{4} = side \\ \\ 15 = side$

So , the side of the square is $\huge\red{15\:cm}$

$Now, \: the \: area \: of \: square = side \times side \\ \\ = > 15 \times 15 \\ \\ = > 225 {cm}^{2} answer$

Hence the area of the square clock is $\huge\fbox\blue{225cm²}$

Hope this helps
