Hello there!

As I am sure you probably know, area of a rectangle is the length x width. In this shape, I just divided each section into a rectangle.

Your answer will be 302cm.

Look at the way bottom area. If you just make that a 21cm x 10cm rectangle, then you have an area of 210cm.

Next, move up to the little "neck". It is 8cm tall, but we don't know how wide. You can see that on one side of it, there is 8cm of wall, and on the other, another 8cm. As you see from the bottom-most dimension, you will see that the total width for the shape is 21cm. Using this data, we can figure that the width of the "neck" is 5cm. So, 5cm x 8cm = 40cm.

Now, we have our last rectangle. It is 4cm tall, and by using our data from the last problem, we know that the width will be 13cm across (5cm+8cm). Simply multiply 13cm x 4cm, and then you will find a area of 52cm.

Finally, just add up your measurements. 210cm + 40cm + 52cm = 302cm.

I hope I haven't made you bored out of your mind... I hope you can use this to solve any other problems that come up in the future!
