Mathplanet. Menu Pre-Algebra / Inequalities and one-step equations / Calculating the area and the perimeter. The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.


The perimeter of a shape is the total distance around it, while area describes the amount of surface the shape uses or covers. Perimeter and area calculation methods differ for every kind of shape. For instance, while you can find the area of a rectangle simply by multiplying its length by its width, a circle requires a more complex calculation.


The perimeter is the length of the entire outside boundary of a polygon, and the area is the measure of the space that fills the polygon boundary. The area and perimeter are extremely useful measurements that can be used in household projects, construction, DIY projects, and in the estimation of materials you might use. For example, the simple act of painting a room requires knowing how much ...


Calculating the area and perimeter of a triangle as well as rectangle will help you figure out how to calculate the perimeter and area of just about any other shape, once you have mastered the skills for calculating the perimeter and area. To calculate the perimeter, you use addition; to calculate the area, you use multiplication.

Best Answer: The usual approach to maximization problems is calculus. You write out the equation for the area in terms of the lengths of the sides: in this case A = xy, where x and y are the side lengths. You know the perimeter is 500ft, so 2x + 2y = 500ft; that means y = 250ft - x. Plugging this into the ...
