Answer: C. The size of a business is ordinal-scaled because it has values that can be used as an order or rank of a categorical variable.

The correct answer is the 5th option (one before the last one).
First symmetrically cut the pentagon to get 5 pieces. (So that you will get the idea that this polygon is divided into 5 triangles)
Then find the area of one of the triangles:
Area of Triangle = 
A = 
× 4 × 10
A = 20 m²
To find the area of the whole pentagon shape:
A = 20 × 5 = 100 m²
