Understanding Area Calculations in Square Meters

Learn how to calculate area and estimate costs in square meters for different spaces.

Area Formulas

Rectangle:

$A = l \times w$

Square:

$A = s^{2}$

Circle:

$A = π r^{2}$

Triangle:

$A = \frac{1}{2} \times b \times h$

Where:

$A$ = Area in square meters
$l$ = Length in meters
$w$ = Width in meters
$s$ = Side length in meters
$r$ = Radius in meters
$b$ = Base in meters
$h$ = Height in meters

Calculation Steps

Measure the dimensions in meters
Select the appropriate shape formula
Substitute the measurements into the formula
Calculate the area in square meters
If needed, multiply area by cost per m² for total cost

Example Calculation

Problem:

Calculate the area and cost of a rectangular room:

Length = 6 meters
Width = 4 meters
Cost per m² = $25

Solution:

Calculate area using rectangle formula: $A = l \times w$
Substitute values: $A = 6 meters \times 4 meters = 24 square meters$
Calculate total cost: $Total Cost = 24 m² \times $ 25 = $ 600$
