A square with a side of 12 cm was cut out of a rectangle with sides of 14 cm and 13 cm.

A square with a side of 12 cm was cut out of a rectangle with sides of 14 cm and 13 cm. Find the area of the remaining figure.

Since, according to the condition of the problem, another figure is cut out from one figure, the area of the remaining figure will be equal to the difference between the areas of the original figure and the cut figure. Thus, to solve the problem, the area of the square must be subtracted from the area of a given rectangle:

14 * 13 – 12 * 12 = 182 – 144 = 38 (cm2);

Answer: the area of the remaining figure is 38 cm2.
