What Does Area Mean in math

Introduction to calculate area of building:

Area is the measure of surface occupied by an object. The standard unit for measurement of area is meter square (m2)however the areas of smaller dimensions can be expressed in mm2or cm2.The areas of large amount of dimensions can be expressed in acre or hectare. Here we have study about how to calculate the area of the building shape image and its example problems.

Calculate area of the building example problems:

Example: 1

Calculate the area of the building which is in the form of square with side length is 6.

Solution:

First we have to draw the image and mark the side length.



Here the building shape is square

We know that area of the square = a 2

a = 6

Substitute a value in the formula we get

Area = (6)2

=36 meter square

Area of the given building is 36 meter square.

Example: 2

Calculate the area of the building which is in the form of rectangle with base is 8 meter and the height of the rectangle is 7 meter.

Solution:

Figure:



Mark the all measurements.

Here the shape is rectangle so we have to find the area of the rectangle

Formula = base *height

Here the given b = 8 meter and h= 7 meter

Substitute the b and h value in the above formula we get

Area = 8*7

= 56 meter square

Example: 3

Calculate the area of the building which is in the form of triangle with base is 12 feet and the height of the rectangle is 9 feet.

Solution:

Draw the diagram for the given measurement and mark the all data.


Here the building shape is a triangle so we have to find the area of the triangle

Formula:

Area = 1/2 (b*h)

Here base is 12 feet and height is 9 feet substitute the above formula we get

Area = 1/2 (12*9)

= 108 / 2

The simplest form is 54

The area of the given triangle shaped building is 54 feet square
