$\sf \large \underbrace{ \underline{Understanding \: the \: Question}}$

Inorder to find area of square, we have to first find out the side of square, Which we can simply find by applying perimeter of square.

So let's do it! :D

★Perimeter of square=4×Side

$\sf➠ \: 84cm = 4 \times side$

$\large\sf➠ \: \frac{84}{4} = side$

21cm=Side

Now apply length of side in the formula of area of square.

★Area of square=Side²

$\sf➠ \: 21 \times 21$

$\sf \large➠ \: 441cm {}^{2}$

So area of square is 441cm²
