Answer:
6x + 2
Step-by-step explanation:
The area of a square is side length times itself.
In this problem, the area of one square is:
x², or x * x. So the side length of each square must be x.
In the rectangular shape, the area would be top * side. The side is equal to x because "side" is equal to the sides of the other squares (because a square's sides are all the same).
Plugging that into the equation, top * x = x, so the top must be 1.
There are 5 "full-length sides" on the two "full" squares on the left. Then, in the last skinny rectangle, there are two "tops", and one "full-length side".
Substitue the values of each side.
5x + 1 + 1 + x = 6x + 2
