Importance of the Math Concept Area

Area. more The size of a surface. The amount of space inside the boundary of a flat (2-dimensional) object such as a triangle or circle, or surface of a solid (3-dimensional) object. In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object. The area of a figure is the number of unit squares that cover the surface of a closed figure. Area is measured in square units such as square centimteres, square feet, square inches, etc.

Area by Counting Squares

May 28, · Definition of Area The mathematical term 'area' can be defined as the amount of two-dimensional space taken up by an object. The use of area has . Area of A = a 2 = 20m ? 20m = m 2. Part B is a triangle. Viewed sideways it has a base of 20m and a height of 14m. Area of B = ?b ? h = ? ? 20m ? 14m = m 2. So the total area is: Area = Area of A + Area of B. Area = m 2 + m 2. Area = m 2. May 30, · Area is a mathematical term defined as the two-dimensional space taken up by an object, notes gooddatingstory.com, adding that the use of area has many practical applications in building, farming, architecture, science, and even how much carpet you'll need to cover the rooms in your house. Sometimes the area is quite easy to gooddatingstory.comted Reading Time: 5 mins.

Use unit squares to understand the concept of area and find area for different two dimensional shapes.

We often find the area of the room floor to determine the size of the carpet to be bought. Covering the floor with tiles, covering the wall with paint or wallpaper or building a swimming pool are other examples, where in the area is computed. In real life, not every plane figure can be clearly classified as a rectangle, square or a triangle. To find the area of a composite figure which consists of more than one shape, we need to find the sum of the area of both or all the shapes forming the composite figure.

The area of the outside surface of a solid or three-dimensional shape is called Surface Area. For instance, a rectangular prism has 6 rectangular bases and lateral faces. So, the total surface area is the sum of the areas of all the 6 rectangles.

Instead of handing out math worksheets on the area to your children, involve them in home improvement projects. Inform them about the room that you are considering to paint. Ask them to calculate the total surface area of the walls, in order to find how much paint is required.

Covers Common Core Curriculum 3. What is Area? In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object. The area of a figure is the number of unit squares that cover the surface of a closed figure. Area is measured in square units such as square centimteres, square feet, square inches, etc. Common simple shapes and polygons have their own formulae for calculating area. Two-Dimensional Geometric Shapes:.

Discuss how all walls of the room may be different and thus, taking overall measurements and then subtracting the area of the door, windows or book shelves, will help in estimating the amount of paint needed. You can also ask to consider finding the total surface area of a present that they wrapping in order to find the amount of wrapping paper required.
