A rectangle with sides of 8cm and 3cm, inside it is a square with a side of 2cm. Find out the area of the resulting figure

To find the area of such a figure, you need to subtract the area of the inner square from the area of the outer rectangle.

1. The area of a rectangle is calculated by the formula S = a * b, where a and b are its sides:
S (rectangle) = 8 * 3 = 24 cm2

2. The area of a square is calculated in the same way as the area of a rectangle, but with the same sides:
S (square) = 2 * 2 = 4 cm2

3. Subtract the area of the square from the area of the rectangle:
24 – 4 = 20 cm2

Answer: the area of the figure is 20 cm2
