Answer :-
Area of the square is 4.5 m².
Solution :-
Length of the diagonal of a square (d) = 3 m
Area of the square = d²/2
= 3²/2
= 9/2
= 4.5 m²
Therefore area of the square is 4.5 m².
Formula used to solve :-
Area of the square = d²/2
where d = Diagonal of the square
Additional information :-
• Perimeter of the square = 2√2 * d
where d = Diagonal of the square
• Length of the side of a square = d/√2
where d = Diagonal of the square
