Question

Find the area of a square if the length of the diagonal is 2.8 metre.
Please answer step by step​

Answer 1

Since a diagonal of a square = the length of the square,

Length = 2.8m
Now,
Area = (side)^2
=> 2.8 * 2.8
.•., Area = 7.84 square metre

Now if you ask me, how can I tell that a diagonal = length of the square?

If you have studied the properties of a square, it should be mentioned that a diagonal of a square is equal to its length making it evident of its area.
