Well, isn't that just a happy little question! To find the square footage of a rectangle, you simply multiply the length by the width. In this case, 30 inches is the length and 40 inches is the width, so when you multiply them together and convert to square feet, you'll have your answer! Just remember, there are 144 square inches in a square foot, so you'll need to do a little conversion at the end.

Oh, dude, you're hitting me with some math right out of the gate! Alright, so first we gotta convert those inches to feet because we're all about that square footage life. So, 30 inches is like 2.5 feet and 40 inches is like 3.33 feet. Multiply those bad boys together and you get 8.33 square feet. Math is fun... kind of.
