Area is the region occupied by a shape. Perimeter is total distance covered by the boundary of a shape. Area is measured in square units (m2, cm2, in2, etc.) Perimeter is measured in units (m, cm, in, feet, etc.) Example: Area of rectangular ground is equal to product of its length and breadth.
- The area is the region covered by shape or figure whereas perimeter is the distance covered by outer boundary of the shape. The unit of area is gi...
- The perimeter of any polygon is equal to the sum of its sides. Perimeter = Sum of all sides
- A circle is a curved shape and its area and perimeter are given by its radius. Area of circle is πr2 Perimeter or circumference of circle is 2πr.
- If a square has side length of 2cm then, Area of square = side2 = 22 = 4cm2 Perimeter of square = sum of all sides = 2+2+2+2 = 8

Perimeter for a 2-dimensional shapeis the total distance around the respective shape. 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. The peripheral border in blue is the perimeter of the park.
The areafor a 2-dimensional shape is the space enclosed within the perimeter of the given shape. 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 the park is shown in dark green color.
Triangle The formulas for calculating the perimeter and area of a triangle ABC are: 1. Perimeter = a + b + c ⇒ Perimeter = sum of the length of all sides ⇒ Perimeter = a + b + c 1. Area = 1⁄2× base × height Square 1. Perimeter = 4a ⇒ Perimeter = sum of lengths of all sides ⇒ Perimeter = a + a + a + a ⇒ Perimeter = 4a 1. Area = a2 ⇒ Area = length × ...
If all the measurements are in centimeter, the units of measurement for the perimeter and area of different shapes are: 1. Perimeter = sum of sides Thus, the unit of measurement remains the same, as cm 1. Area = product of sides The unit of measurement is unit2 or cm2 Application The concepts of area and perimeter are the basis for understanding Eu...
- Start with an anchor chart. Start with an anchor chart! This clever option lays out the differences and similarities between area and perimeter measurements, and the color coding will help students use it while solving problems.
- Decorate your classroom. Use your classroom—doors, bulletin boards, tables—to reinforce the idea of area and perimeter. Students can refer to the decor to reinforce the concept, and if you need to reteach, you have a tool at the ready.
- Use four square tiles. ADVERTISEMENT. Once students understand what area and perimeter are, they work with four square blocks in this investigation to see how many ways they can create shapes with four blocks and calculate the area and perimeter of each shape they make.
- Solve a ribbon square problem. The ribbon square problem is a more advanced application of area and perimeter, and it’s a great way to stretch higher learners who have really mastered the concepts.

4 days ago · Perimeter is the distance around a 2-dimensional figure, and it can be calculated by adding together the lengths of the figure's sides. Area is the amount of 2-dimensional space that a shape covers. For squares and rectangles, it's calculated by multiplying together the figure's length and width.
