Find the area of each figure. 1. A rectangle with sides 7 mm and 4 mm. 2. A square grid.

Step 1: Figure 1 (rectangle)

The area $A$ of a rectangle is given by
$A = l \times w,$
where $l$ is the length and $w$ is the width.

$l = 7$ mm and $w = 4$ mm.

Substitute the values:
$A = 7~mm \times 4~mm = 28~square mm.$

28

Step 2: Figure 2 (square)

The area $A$ of a square is given by
$A = s^2,$
where $s$ is the side length.

$s = 2$ mm.

Substitute the value:
$A = (2~mm)^2 = 4~square mm.$
