Answer:

5.3 in

Explanation:

The property of a square is that the width and height are equal.

The formula of area of a rectangle (a square is a rectangle) is A=bh

In this case, since the width and height are the same, we can substitute b with h or h with b.

A=b^2

28=b^2

Square root both sides

We can find that b=5.29 which rounds 5.3
