If the length and width of a rectangle each doubled what happens to the area of the rectangle

Hatshy [7]

It would quadruple.

Basically, it will quadruple because you are multiplying, which doesn't make much sense actually.

An example is with a 2 by 2 figure, you would get 4 squared as the area, but if you double both sides, 4 by 4, you would get 16 squared as the area.

Why learn this:

Order of operations is a basic rule of algebra. It tells us what to solve first when we have an equation with multiple functions, which is something that you will likely encounter throughout your math studies. The order is: Parentheses, Exponents, Multiplication and Division, then finally Addition and Subtraction. Remember that when you're solving within the parentheses, the Order of Operations applies!
