Elizabeth is trying to find the missing side length. Here is her work. What mistake did she make?

• She added incorrectly. 3+4 is not 7.

• She added the side lengths instead of the areas. She should square 3 and 4 BEFORE adding.

• She used the wrong hypotenuse. 4 is the longest side.

• She should multiply 3 and 4 to get 12.
