What are the people on Wattpad good at? Reading and writing, of course! Who needs math? What is math?
I'm a math nerd here, ready to help anyone understand any question they can ever have about math. I'll try to give simple and clear explanations. S...
Say you have a problem like this: What is the area of a rectangle with side lengths of 8 cm and 4 cm?
Most of you already know what this is asking. But here's a brief explanation if you don't. The area refers to the total space enclosed by a shape. It is not the distance around the shape--that's called the perimeter. Here's a picture to give a visual on what area and perimeter are:

The equation for finding the area of a rectangle like in the example is length times width, or:

It doesn't matter which side you label which; the equation will be the same. It is also worth noting that on a rectangle, opposite sides have equal lengths.
This equation is very basic and easy to remember, but if you have a hard time recalling it, try thinking about it this way:

So what if you're trying to find the area of different shapes? What if you're given a triangle with a base of 6 cm and a height of 3 cm? The known formula for area is one half times base times height, or:
