How to Find the Area of a Rectangle

Below is a video showing how to find the area of a rectangle exactly. A rectangle is one of the easier geometrical shape to do calculations with. If you know how to find the area of a rectangle, then you know how to find the area of a square. Knowing how to find the area of a rectangle is the basis of knowing how to find the area of other quadrilaterals.

Another great calculation concerning a rectangle is how to find the perimeter of rectangles which we will discuss later. Teachers are often teaching area of rectangles and triangles together because they are very similar. Finding the area of a rectangle using algebra leads to the proof of the formula for the area of a rectangle. When your rectangle is 3 dimensional, you can find the surface area of the rectangle. Watch the video below to learn how to find the area of a rectangle.
