## The Area Of Plane Figures Example Problems with Solutions

Example 1: Find the area of a square whose side is 8 cm.Solution: Area of square= side × side= 8 cm × 8 cm= 64 cm2

Example 2: Find the area of a rectangle whose length is 21 cm and breadth is 5 cm.Solution: Area of a rectangle= length × breadth= 21 cm × 5 cm= 105 cm2

Example 3: The side of a square plot of land is 30 m. Find the cost of levelling the plot, if the rate is Rs 2 per square metre.Solution: Area of square= side × side= 30 m × 30 m= 900 m2Levelling cost of 1 m2= Rs. 2Levelling cost of 900 m2= Rs. (2× 900)= Rs. 1800

Example 4: Find the area of the given figure.Solution: Area of the rectangle DEFG = l × b= 7 cm × 3 cm = 21 cm2Area of the rectangle ABCG  l × b= 7 cm × 3 cm = 21 cm2Area of the complete figure= Area of rectangle DEFG= 21 cm2 + 21 cm2= 42 cm2

Example 5: How many tiles, each measuring 2 m by 1 m, are required to cover a rectangular hall 12 m long and 8 m broad? Find the cost of tiles at Rs. 25 per tile.Solution: Length of a tile = 2 mBreadth of a tile = 1 m∴ Area of each tile = 2 m × 1 m= 2 m2Length of rectangular hall = 12 mBreadth of rectangular hall = 8 m∴ Area of the hall = 12 m × 8 m= 96 m2Hence, number of tiles required= Area of the hail/Area of one tile= 96/2 = 48∴ Cost of tiles 48 × 25= Rs. 1200
