Imara used these steps to find the length of the hypotenuse of the right triangle.

3 squares are positioned to form a right triangle. The small square is labeled 15, medium square is 20, and large square is not labeled.

Step 1: Find the area of the square with side lengths of 20: 400

Step 2: Find the area of the square with side lengths of 15: 225

Step 3: Find the sum of the areas of the two squares: 625

Step 4: State the length of the hypotenuse: 625

Which best describes Imara's error?

She should have found the area of the square with side lengths of 15 first.

She did not correctly calculate the area of the square with side lengths of 15.

She should have found the sum of 15 and 20 and then squared the sum.

She did not find the side lengths of the square with an area of 625.
