Question
The polygons are regular polygons. Find the area of the shaded region to the nearest tenth
(An image bellow of a white box inside a shaded box. The white box has a line from the center to the corner labeled 4cm. The shaded box has the same thing but it's 9cm)
This has confused me a lot and I keep getting different answers. I would appreciate some help.

I appreciate the help, but my problem here didn't actually give me any sides to figure out how I was going to find the area ;-; Thanks for trying to help though!

in the white box, half the diagonal is 4. If the box is a square, then the area is 1/2 d^2 = 1/2 * 8^2 = 32
Similarly, the large box has area 1/2 * 18^2 = 162
So I guess the shaded area is 162-32 = 130
Similarly, the large box has area 1/2 * 18^2 = 162
So I guess the shaded area is 162-32 = 130
