Answer:

Explanation:
In general, the area is defined as the region occupied inside the boundary of a flat object or 2d figure.
The measurement is done in square units with the standard unit being square meters (m 2).
As, it is mentioned each square 1 unit square and each half square is half square unit.
So, by calculating each 1 square unit and half square units in the figure, we find Area.
The area of each figure A is 8 cm².
The area of each figure B is 8 cm².

Question 2.
What is the area of the figures?
Answer: 8 cm²
Explanation:
