Definition: - The area of a surface, whose each equal side is equal to one meter is called square meter and it is also known as meter square (m^2).
This figure shows a square where all the four sides are equal to 1 meter.
Hence the area of surface enclosed by four sides is 1 square meter or 1 meter square.
1 square meter is the standard international (SI) unit
of measuring area of a surface.
Sub- multiples of standard unit area: -
♦ 1 square centimeter (cm ^2)This figure shows a square where all the four sides are equal to 1 meter.
Hence the area of surface enclosed by four sides is 1 square meter or 1 meter square.
1 square meter is the standard international (SI) unit
of measuring area of a surface.
Sub- multiples of standard unit area: -
♦ Hectare
♦ One square kilometer (km ^2)
Relation between 1 square meter, centimeter square and hectare: -
1 m^2 = 1 m * 1 m
= 100 cm * 100 cm
= 10000 cm^2
= 10 ^4 cm^2
Therefore, 1 m^2 = 10^4 cm^2
1 hectare = 100 m * 100 m
1 hectare = 10000 m^2
1 hectare = 10^4 m^2
Therefore 1 m^2 = 10 ^ (-4) hectare
1 km^2 = 1000 m * 1000 m
=1000000 m^2
= 10^6 m^2
1 m^2 = 10 ^ (-6) km^2
Question 1: - A school hall measure 20 m in length and 12 meters in breadth. Find its area in square meter.
Solution: - Area of school hall = length * breadth
= 20 m * 12 m
= 240 m^2
Question 2: - The length of a school compound is 450 m and breadth is 145 m. find the area of the compound in square meter.
Solution: - Area = length * breadth
= 450*145 m^2 = 65250 m^2
