Answer: 76%
Step-by-step explanation:
In the first square, all 25 parts are shaded.
In another sqaure, 13 out of 25 qual parts are shaded.
Now, in both the squares
Total parts = 25+25 =50
Total shaded parts = 25+13 = 38
The percent of shaded area = [tex]\dfrac{\text{Total shaded parts}}{\text{Total parts}}\times100\%[/tex]
[tex]=\dfrac{38}{50}\times100\%\\\\= 76\%[/tex]
Hence, 76% is represented by the shaded area.
