Ascience fair poster is a rectangle 4 feet long and 3 feet wide. what is the area of the poster in square inches?

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!

The answer is 144 inches squared.
