|Class 6 Maths Mensuration||Area|
The amount of surface enclosed by a closed figure is called its area.
Area of a Square:
Area of the square = side × side = l2
Area of a Rectangle:
Area of a rectangle = (length × breadth)
Problem: The area of a rectangular garden 50 m long is 300 sq m. Find the width of the garden.
Let the width of the garden be of b m.
Since the garden is rectangular in shape, we get :
Area of a Rectangle = length * breadth = 50*b
50*b = 300
b = 300/50
b = 6 m
The width of the garden is 6m.
Problem: A floor is 5 m long and 4 m wide. A square carpet of sides 3 m is laid on the floor. Find the area of the floor that is not carpeted.
Area of the rectangular floor = length*breadth = 5*4 = 20m2
Area of the square carpet = Side2 = 3*3 = 9m2
Remaining area on the floor = (20 -9) m2 = 11m2
