Let's separate this shape into three parts. A smaller rectangle at the top, and one at the bottom, and a bigger rectangle in the middle.
The smaller rectangle at the top:
The equation to find the area of a rectangle is
(a = area, l = lenght, w = width)
a = l · w
Put in the values
a = 18 · 3
a = 54
Since the smaller rectangle at the bottom has the same length and width, it has the same area.
The bigger rectangle in the middle:
a = l · w
Put in the values
a = 8 · 9
a = 72
Now add all of the areas together to get the answer!
72 + 54 + 54 = 180
The answer is 180 :)
Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)
