can someone please help? im really confused.

Given:
Each big square represents one whole.
To find:
The percent represented by the shaded area.
Solution:
One big square have 100 small square.
Shaded part of first big square = 100
Fraction of shaded part of first big square = [tex]\frac{100}{100}[/tex]
Shaded part of second big square = 19
Fraction of shaded part of second big square = [tex]\frac{19}{100}[/tex]
Fraction of total shaded area:
[tex]$=\frac{100}{100}+\frac{19}{100}[/tex]
[tex]$=\frac{100+19}{100}[/tex]
[tex]$=\frac{119}{100}[/tex]
Percent of shaded area:
[tex]$=\frac{119}{100}\times 100\%[/tex]
= 119%
The shaded area is 119%.
