Question

Answer 1

$\textbf{ Hello Mate! }$

Thanks for your question!

Area of square = half of product of diagonals

[ Since, it is a square so both diagonals will be of same length ]

$area = \frac{1}{2} \times 72 \: cm \times 72 \: cm \\ \\ = > 36 \: cm \times 72 \: cm \\ \\ = > 2592 \: {cm}^{2}$

Thus, area of square is 2592 sq. cm

Have great future ahead!

Answer 2

Since diagonal of the square is equal to the side of the square
$therefore \: \\ area \: of \: square = 72 \times 72 \\ \\ 5184cm { }^{2}$
