# Find the area of the filled part of the rectangle if the area of the unpainted part is 40%

**Find the area of the filled part of the rectangle if the area of the unpainted part is 40% of the entire area of the rectangle. With a rectangle length of 16 cm and a width of 5 cm**

Let’s find the value of the area of this rectangle, for this it is necessary to multiply the value of the length of this rectangle by the value of the width of this rectangle:

16 * 5 = 80 cm2 – the value of the area of this rectangle;

Let’s find the value of the area of the unpainted part of the rectangle, for this we need to find 40% of the entire area of this rectangle:

80 * 40% = 32 cm2 – the value of the area of the unpainted part of this rectangle;

Let’s find the value of the area of the filled part of this rectangle, for this it is necessary to subtract the value of the area of the unpainted part of this rectangle from the value of the entire area of the rectangle:

80 – 32 = 48 cm2 – the value of the area of the filled part of this rectangle.

Answer: 48 cm2 – the value of the area of the filled part of this rectangle.
