Asquare has a diagonal with length 12.2. what is the area of the square to the nearest tenth?

Area of the square is 74.4 unit².

Step-by-step explanation:

A square has a diagonal with length 12.2 units.

We have to find the area of the square.

Since all angles of a square are of 90° so by Pythagoras theorem

Side² + side² = Diagonal²

Let the length of the diagonal is d and length of sides be l.

l² + l² = d²

2l² = d²

Since area of a square = side² = l²

Therefore area of square =

Area of the square is 74.4 unit².
