Answer: [tex]100\text{ sq m}[/tex]
Step-by-step explanation:
From the given picture, it can be seen that the side length of square ABCD = 10 m
We know that the area of square is given by :-
[tex]\text{Area of square}=side^2[/tex]
Therefore, area of square ABCD is given by :-
[tex]\text{Area of square ABCD}=(10)^2=100\text{ sq m}[/tex]
Hence, the area of square ABCD[tex]=100\text{ sq m}[/tex]
