Must find the length and the width of the figure of figures depending on how you decide to do it
Separate the figure into 2 or 3, following the lines given. Say you were to have divided it horizontally, leaving you with 2 figures. One of which has the dimensions 4cm, 3cm, and 4cm on it. The other with the dimensions, 4cm, 3cm, 4cm, and 3 cm on it.
Start with the first figure. The dimensions of Length and Width are already given to you. 4 times 3 gives you 12, meaning the area of the first figure is 12cm^2.
Now the second figure. This one is a tad bit more difficult as it requires you to piece information together. Start with length. We have the dimension 4cm, and on the other side another 4cm, however just above that is a 3cm dimension that completes this side. Together the length of this one is 11 cm. Next, on to the width. This is easy as it is already provided, 3cm. Multiplied by one another, 3cm times 11cm gives us 33cm^2.
Now to add the two figures together. The first figure has a total area of 12cm^2 and the second a total area of 33cm^2. In total, the entire plane has a total area of 45cm^2.
