# 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.
