In mathematics the area of a plane figure refers to the number of square units the figure covers. The area is the inside shape or space measured in square units. In rectangles and in squares, a simple calculation of length and width will give the number of square units. The square units could be inches, centimeters, yards etc. or whatever the requested unit of measure asks for. There are many formulas used to determine the area of many common shapes or polygons. The amount of surface?enclosed by a closed figure is?called its?area.
The following conventions are to be adopted while calculating the area of a closed figure using a squared or graph paper.
Count the fully-filled squares covered by the closed figure as one square unit or unit square each.Count the half-filled squares as half a square unit.Count the squares that are more than half-filled as one square unit.Ignore the squares filled less than half.
For example, the area of this shape can be calculated as shown:
Covered areaNumberArea estimate (sq. units)Fully filled squares66Half?filled squares77 x ?Squares filled more than half00Squares filled less than half00
Area covered by full squares = 6 x 1 = 6 sq. units.
Area covered by half squares = 7 x ? = 7/2= 3 ? sq. units
Total area of the given shape = 6 + 3 ? sq. units
Thus, the total area of the given shape = 9 ? sq. Units
Area of a rectangle can be obtained by multiplying length by breadth. Area of the square can be obtained by multiplying side by side.
Area of a Rectangle
The area of a polygon is the number of square units inside the polygon. To understand the difference between perimeter and area, think of perimeter as the length of fence needed to enclose the yard, whereas area is the space inside the yard. Perimeter is 1-dimensional and is measured in linear units such as inches, feet or meters. Area is 2-dimensional: it has a length and a width. Area is measured in square units such as square inches, square feet or square meters. ?
To find the area of a rectangle, multiply the length by the width. The formula is:
Area of a rectangle = (length ? breadth)
Let's look at some examples of finding the area of rectangles.
Example 1:? A rectangle has a length of 8 centimeters and a width of 3 centimeters. Find the area. ?
Solution:?A = L.W
A = (8 cm) ? (3 cm) = 24 cm?2
In Example 1, we found the area given the dimensions of the rectangle. Let's look at some examples in which we are given the area of the rectangle, and are asked to work backwards to find the missing dimension.
?Example 2:?The area of a square is 9 square centimeters. How long is one side???
Solution: ?A = s.s
9 cm?2?= s ??

Water is a compound made up of hydrogen and oxygen, so pure water would be water that contains nothing but hydrogen and oxygen. However, pure water of this sort does not normally exist except in the controlled environment of a laboratory. Even in a laboratory pure water is hard to come by.If you want to know if your home's drinking water contains unsafe levels of lead, have your water tested. Testing is the only way to confirm if lead is present or absent. Some faucet and pitcher filters can remove lead from drinking water.A physical test for pure water is testing the boiling or freezing point. Pure water will boil at 100 degrees Celsius and freeze at 0 degrees Celsius. One chemical test is to use cobalt chloride paper - the paper will turn from blue to pink in the presence of water.If you want to know if your home's drinking water contains unsafe levels of lead, have your water tested.
