81 square inches

Step-by-step explanation:

9*9 = 81

To find the area of a square, we multiply the length by its width

In this case, the length and width of the square area are both 9!

We know this becasue it says "each side of a square piece of cardboard is 9 inches long"

Now let's solve the problem

Area = L × W

Area = 9inches × 9inches

Area = 81 inches²

*I put the "²" above inches because any area of a square is just multiplying the same number by itself or ... in other words... "squaring it"

[ex: 9² = 9 × 9]
