Calculating Area - Cycle 2

Some figures may contain half squares. Two half squares form a whole square unit.

Follow these steps to calculate a figure’s area.

1. If there are any half squares, join them to form whole-square units.
2. Count the total number of square units, including those formed using the half squares.

What is the area of this figure?

I join half squares to form whole-square units. I obtain 2 square units with the 4 half squares.
I count the total number of square units, including those formed using the half squares.

This figure’s area is 12 square units.

If a figure has an odd number of half squares, calculate the total area of the figure in terms of half-square units. To do this, each square unit must be divided into two half squares.

Example:

This figure has an area of 23 half squares.
