Answer:
3 square centimeters
Step-by-step explanation:
Split the shape up into two pieces, you should end up with a square that is 1 cm by 1 cm and a rectangle that is 1 cm by 2 cm. By calculating the areas and adding them up together, you get a total area of 3 cm^2.
1 x 1 = 1 cm^2
1 x 2 = 2 cm^2
1 + 2 = 3 cm^2
