Answer:
take your pick. Each has its own reason.
Step-by-step explanation:
As with a lot of "doesn't belong" problems, the one that is different depends on your criteria. In the attached figure, each one "doesn't belong" for a different reason. Those reasons are listed below each number line.

I might choose the lower left: "addition, not subtraction", as it is the only one with arrows in the same direction. That makes its difference from the others more obvious, perhaps.
Answer
The total area of the squares = 29 square cm
The triangle is not a right-angled triangle
Step-by-step explanation:
We are given three squares
The first square has a length of 4cm
The second square has a length of 3cm
The third square has a length of 2cm
Part A
Total area = Area of square 1 + Area of square 2 + Area of square 3
Area of a square = l^2
Where l is the length of the square
Area of a square 1 = 4^2
Area of a square = 16 square cm
Area of square 2 = 3^2
Area of square 2 = 9 square cm
Area of square 3 = 2^2
Area of square 3 = 4 square cm
Total area of the square = 16 + 9 + 4
The total area of the square = 29 square cm
Hence, the total square of the figure is 29 square cm
