Answer:
52%
Explanation:
In the box that is fully filled with squares, it can be shown as a 100%
There is a total of 25 squares and only 13 is shaded, so you can use a formula to find the percentage
×100= 52%
Hope it is right, ask any questions if unsure :)
The answer was actually 152% as they is a fully filled square on the left side so you had to add the 100 and 52 which gives 152%
