Also, we use these formulas for calculating the area and perimeter for quadrilaterals and polygons comprising of sides and curves. The concepts of area and perimeter are the basis for understanding Euclidean geometry and calculating the volume of solid shapes in 3-dimensional space such as cones, prism, sphere, and cylinder. Thus, the unit of measurement remains the same, as cm If all the measurements are in centimeter, the units of measurement for the perimeter and area of different shapes are: ⇒ Perimeter = sum of lengths of all sides
⇒ Perimeter = sum of the length of all sides The formulas for calculating the perimeter and area of a triangle ABC are: The area for the park is shown in dark green color.Ĭalculating Area and Perimeter for Different Shapes Triangle To calculate the area for different shapes, use different formulas based on the number of sides and other characteristics such as angles between the sides. The area for a 2-dimensional shape is the space enclosed within the perimeter of the given shape. The peripheral border in blue is the perimeter of the park. For the figures with straight sides such as triangle, rectangle, square or a polygon the perimeter is the sum of lengths for all the sides. Perimeter for a 2-dimensional shape is the total distance around the respective shape. Keywords: perimeter, area, rectangle, unit squares, square, triangle, practice, math, sides Calculating Area and Perimeter for Different Shapes.
