Answer» In area of a SQUARE we will learn how to find the area by counting squares. To find the area of a region of a closed plane FIGURE, we draw the figure on a centimeter squared PAPER and then COUNT the number of squares enclosed by the figure. We know, that square is a rectangle whose length and breadth are equal. In a square all four sides are equal.
THEREFORE, area of a square = (side × side) square units = (side)2 square units. Square 0Save Square 0Save In a square the length is equal to breadth. Hence, area of a square = side × side The number of 1 cm squares enclosed = 4 Area = 4 sq cm 4 = 2 × 2 Hence, area = side × side The unit of sides and the corresponding units of areas as given below: Unit of Side Unit of Area mm square mm (sq mm) or mm2 cm square cm (sq cm) or cm2 m square m (sq m) or m2 km square km (sq km) or km2 Note: Write finding the area of a given figure, make sure that the sides (length or breadth) are in the same unit of length. If they are given in different units, change them to the same unit. |
