NCERT Solutions for Class 6 Maths Chapter 10 Mensuration: Mensuration means measurement. In NCERT Solutions for Class 6 will study how to measure the length along the boundary of a closed figure and how to find the space occupied by a closed figure. The distance covered along the boundary of a closed figure is known as perimeter and the space occupied by a closed figure is known as area. In the NCERT Solutions for Class 6 Maths Chapter 10, we will discuss the perimeter of a rectangle, square and a triangle if side lengths are known. And also we will study about how to find areas of figures by counting squares also in NCERT Solutions for Class 6 Maths Chapter 10 Mensuration we will study how to find the area of rectangle and square using the side of the square, length, and breadth of the rectangle.
In many situations in real life, we will use the concept of perimeter and areas. One such situation is if we need to cover the rooftop of a candle in the shape of a rectangle how mutch sheet is needed is decided by the area of the roof. Below are the formulas used to calculate perimeter and area of figures mentioned in the NCERT Solutions for Class 6 Maths of this chapter.
Area and perimeter of rectangle: Area of the rectangle with length l and breadth b is the product of length and breadth = lb. The perimeter= l+b+l+b=2(l+b)
Area and perimeter of a square: All the 4 sides of a square are equal. If the length of a side of the square is l then perimeter= 4l and area= l2
The perimeter of a triangle: A triangle has three sides. If the length of sides is a, b and c then the perimeter is a+b+c. For an equilateral triangle, all the sides are equal and if one of the side lengths is l then the perimeter of an equilateral triangle is 3l.
10.2.1 Perimeter of a rectangle
10.2.2 Perimeter of regular shapes
10.3.1 Area of a rectangle
10.3.2 Area of a square
