Hi there!
To solve this problem, first, we need to find the area of the poster in square feet, and then convert it into inches.
Since the formula for finding the area of a rectangle is length * width, we do just this:
4 * 3 = 12
So, the area is 12 feet squared.
Now, since
1 ft = 12 in,
We can multiply the area of 12 by 12.
12 * 12 = 144
So, the answer is 144 inches squared.
Hope this helps!
