One of the areas that many young math students struggle with is perimeter. However, with a little effort, students will find that perimeter is actually quite easy to understand. Perimeter can best be defined as the “boundary,” of a shape, meaning how much area is taken up around the shape. When finding the “perimeter” of a circular area, the solver is said to be finding the circumference. While there are many areas of math that are not actually useful in every day life, perimeter is not one of these. People who put down fences must calculate the perimeter of a yard, and those who design cars must know the circumference of the tire to determine how far it will go. So students who are wary of learning how to solve perimeter problems should remember these strong examples and should know that they just might need this knowledge someday.

One of the first things students will likely learn when studying perimeter is how to find the Perimeter Of A Rectangle. Fortunately, the Rectangle Perimeter Formula is actually quite straightforward. The formula can best be expressed as two multiplied by the length of the rectangle added to two multiplied by the width of the rectangle. Many mathematical textbooks will commonly express the Rectangle Perimeter Formula as 2L x 2W, so students should not be confused if they see it written in this manner. While many problems will be accompanied by drawings of the rectangular figure, some problems will be expressed as word problems. A tip that many students find helpful is to draw or quickly sketch the figure and to fill in the appropriate measurements. More tips are available at Arithmetic.com, a website that provides helpful information on all things math related, enabling students to excel.
Finally, it is important to note that the only reason the rectangular formula is so easy is because a rectangle is a simple shape. It has four sides and the opposite sides are congruent or equal. Thus, students have a simple formula to follow. Different shapes merit different formulas.
