Question

find the area of the shape. (some measurements are shown.) square millimeters

Explanation:

Step1: Divide the shape into rectangles

We can divide the given shape into two rectangles. One rectangle has dimensions 6 mm (height) and 2 mm (width), and the other has dimensions (3 + 3) mm (length) and 1 mm (width).

Step2: Calculate area of first rectangle

The area formula for a rectangle is $A = l\times w$. For the first rectangle with $l = 6$ mm and $w=2$ mm, $A_1=6\times2 = 12$ $mm^2$.

Step3: Calculate area of second rectangle

For the second rectangle with $l=(3 + 3)=6$ mm and $w = 1$ mm, $A_2=6\times1=6$ $mm^2$.

Step4: Find total area

The total area $A$ of the shape is the sum of the areas of the two rectangles, $A=A_1 + A_2=12+6 = 18$ $mm^2$.

Answer:

18 square millimeters
