You did #1 correctly.
#2). The question gives you the equation, and the numbers to use for 'a' and 'b', and it just wants you to plug in those numbers and do the arithmetic.
It says: The number of tiles needed is (a²) divided by (b²).
Then it says: a = 96 and b = 8. I know you can handle that !
Number needed = (96)² divided by (8)² . Use your calculator: (96)² = 9,216 (8)² = 64 Number needed = (9,216) divided by (64) = 144 tiles
#3). While reading #3 carefully, I realized that there's a table printed near it, and you need the table to do the problem. But you can't see the table in the picture, so we're stuck on this one.
To solve math problems, start by understanding what is being asked, express the problem mathematically, plug in known values, perform calculations, and double-check your work. Practice with different types of problems will improve your skills over time. Seek help when needed to clarify any confusion.
