Is this correct? If not please tell the correct answer and how u got it

Answer:
Its incorrect
Step-by-step explanation:
Area is width times height but in this case its 3 numbers so after you did width time height if I'm not mistaken you multiply that number by 4 so you were supposed to multiply 5 and 6 the answer is 30 and then multiply 30 by 4 which is 120 I think.
