Answer:
66 square inches
Step-by-step explanation:
First we have to find out the area of the original piece of metal. Since it is 9 by 9, we can multiply to find that it is 81 square inches. If we remove a 5 by 3 piece, which is equal to 15 square inches, we can subtract 15 from 81 to get the answer - the remaining metal is 66 square inches
