Answer:

[tex]C.\ Area = 0.4 * 0.7[/tex]

Step-by-step explanation:

See attachment for grid

From the attachment:

There are 10 cells on the horizontal axis and there are also 10 cells on the vertical axis.

This implies that, the measurement of each cell is:

[tex]Each\ Cell = \frac{10}{10 * 10}[/tex]

[tex]Each\ Cell = \frac{1}{10}[/tex]

[tex]Each\ Cell = 0.10[/tex]

The horizontal axis has 7 selected cells.

This measures

[tex]Horizontal = 7 * 0.10 = 0.70[/tex]

The vertical axis has 4 selected cells.

This measures

[tex]Vertical = 4 * 0.10 = 0.40[/tex]

So, the selected area is:

[tex]Area = Vertical * Horizontal[/tex]

[tex]Area = 0.40 * 0.70[/tex]

or

[tex]Area = 0.4 * 0.7[/tex]
