Perimeter is the distance around the outside of a shape. For example, if you walk around the edge of a playground, you're measuring its perimeter. Area is the amount of space inside a shape. For example, if you want to put new tiles on your kitchen floor, you need to know the area of the room to know how many tiles to buy.
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.

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...

Area is defined as space or the region occupied by a shape, whereas perimeter is defined as the boundary or the outline of a shape. Two shapes with the same areas can have a different value for the perimeter. The area is measured in square units, whereas the perimeter is measured in linear units.
