To calculate the areas of the two figures, we need to count the number of unit squares in each shape. Each square has a side length of 1 unit, so the area of each figure is simply the number of these squares.

Figure D:

• The shape consists of several unit squares. By counting the squares covered by the shape, we can determine the area.
• It looks like the shape covers 6 unit squares.

Thus, the area of Figure D is 6 units².

Figure E:

• Similarly, for this figure, we count the number of unit squares the shape occupies.
• This shape covers 8 unit squares.

Thus, the area of Figure E is 8 units².
