Equations With Area And Perimeter Worksheet

8 problems

In Mathematics, area is the region that is occupied within the shape. It is the region that is bounded by the shape of a particular object. The area of a geometric shape depends on the properties and dimensions of the shape. Perimeter is the total space around the shape. It is the length of the external boundary of the shape. Both, area and perimeter are relevant for two-dimensional shapes.

Teaching Area and Perimeter Easily


  •  Length: It is the longest dimension of an object. It displays how long an object is. Usually represented by 'L'.


  •  Breadth: It is the shorter dimension of a figure. It shows how broad an object is. It is expressed using 'b'.


Here is an example to solve a question on area and perimeter equations. Let's look at the example mentioned below to understand the concept of area and perimeter.


Q. The length and breadth of a rectangle boundary is 3 cm and 4 cm. Find the area and perimeter of the boundary.


Step 1: Convert the Breadth and Length into the same measurement.


Length = 3cm

Breadth = 4 cm


Step 2: Use the area and perimeter formula based on the shape.



Area of rectangle = length * breadth

3 cm * 4cm = 12cm square units.


Perimeter of Rectangle = 2 ( length + breadth )
