Answer:
Side length of the patch = 1.5 inch.
Explanation:
Area of square = a², where a is the side of the square.
Here area is given by 2.25 square inches.
So, we have a² = 2.25 inch²
So, side of the square is given by [tex]\sqrt{2.25}[/tex]
Side of square, a = 1.5 inch
Side length of the patch = 1.5 inch.
