A square green rug has a blue square in the center. the side length of the blue square is x inches. the width of the green band that surrounds the blue square is 6 inches. what is the area of the green band

square inches.

Step-by-step explanation:

Given:

A square green rug has a blue square in the center.

The side length of the blue square is x inches as shown in the figure:

The width of the green band that surrounds the blue square is 6 inches.

Question asked:

What is the area of the green band ?

Solution:

Side length of blue square =

First of all we will calculate area of blue square.

As we know:

Thus, area of blue square =

Now, we will calculate area of square green rug:

Side length of green rug = Side length of blue square + width which surrounds the blue square

Side length of green rug =

Thus,  area of square green rug =

Now, we will find area of the green band ( shaded region with green color as shown in the figure)

Area of the green band = Area of square green rug -  Area of blue square        

Therefore, the area of the green band is square inches.

b. the decimal could be two-tenths.
