Answer:
she did not find the side lengths of the square with an area of 625.
Explanation:
Imara committed an error, she has calculated the area of the square formed by the hypotenuse of the right angled triangle with sides 15 units and 20 units instead of calculating the length of the hypotenuse of the right angled triangle.
The geometry formed could be seen with the figure attached to the answer.
Hence last option is correct: She did not find the side lengths of the square with an area of 625.
