The width and area of the Rectangular tag is 10 centimeters and 40 centimeters square.
As per the question statement, The perimeter of a rectangular price tag is 28 centimeters. Its length is 4cm. We are supposed to find its width and area.
Let width be [tex]w[/tex]
Perimeter = [tex]2(length*width)[/tex]
[tex]28=2(4+w)\\w=14-4\\w=10cm[/tex]
Hence width is 10 cm
Now area of rectangle = [tex]length*width[/tex]
Area = [tex]4*10=40cm^{2}[/tex]
Hence area is 40 centimeter square.
Therefore the width and area of the Rectangular tag is 10 centimeters and 40 centimeters square.
