The area of a shaded region is the amount of space it occupies
The measurement that is closest to the area of the shaded region is 19 square inches
Start by calculating the area of the big rectangle.
Assume the dimensions of the rectangle are 10 by 15 inches.
The area would be
[tex]A_1 =10* 15[/tex]
[tex]A_1 = 150 in^2[/tex]
Next, calculate the area of the small rectangle.
Assume the dimensions of the rectangle are 13 by 10 inches.
The area would be
[tex]A_2 =13* 10[/tex]
[tex]A_2 =130 in^2[/tex]
Next, calculate the difference between both areas
[tex]d = 150 - 130[/tex]
[tex]d = 20\ in^2[/tex]
19 is the closest to 20
Hence, the measurement that is closest to the area of the shaded region is 19 square inches (using the assumed values)
