A protractor is used to measure angles.
The answer depends on what information you have about the shapes.
You measure or calculate the area. How you do that will depend on the shapes involved.
Surface area of shapes can be measured in square centimetres
Mainly to draw or measure angles of lines or shapes on paper.
A protractor is used to measure angles.
There are formulas for regular shapes. Not all shapes have formulas; for these you can fill them with liquid and measure or weigh the contents.
Angles do not have areas because they are not closed shapes.
A Planimeter.
The answer depends on what information you have about the shapes.
Divide it into regular shapes which are calculable, and then add each of the (divided) shapes back together for your answer.

One method is to divide it into regular shapes - rectangles, triangles, etc. - and measure the areas of those shapes.
