Answer 1

I don’t have the polygon picture — I only see the five numbers (20 cm, 16 cm, 6 cm, 2 cm, 4 cm). Could you either upload the diagram or describe how those lengths are arranged (which are horizontal/vertical and in what order around the shape)?

If you want to proceed while I wait, here are two quick ways I’ll use once I can see/confirm the figure:

1. Break the polygon into rectangles (or a big rectangle minus a smaller rectangle). Compute each rectangle’s area (length × width) and add/subtract to get the polygon area.

2. If the side lengths are given in order around a rectilinear polygon, I can place them and find the missing segment lengths from the equalities of opposite overall dimensions, then compute areas of the pieces.

Also: the correct unit for area is cm².

Send the picture or a short description (for example: “start at top-left corner, go right 20 cm, down 16 cm, left 6 cm, up 2 cm, left 4 cm, up ? cm…”) and I’ll compute the area.
