A square of side 4 cm has a 1 cm by 2 cm rectangle cut out from a corner. What is the area of the remaining shape?

Explanation:
Think of area as the amount of space inside the shape. The square has side 4 cm, so its area is 4 × 4 = 16 cm^2. A 1 cm by 2 cm rectangle is cut out, removing 1 × 2 = 2 cm^2. Subtracting the missing piece from the whole gives 16 − 2 = 14 cm^2. The remaining shape therefore has area 14 cm^2.
