#### About Class 6 Maths Chapter 10

In 6 Maths Chapter 10 Mensuration, we will study about the perimeter and area related to various 2-D figures. This chapter is important as per further classes also. We should learn the formulae of perimeter and areas of various figures. Some the the formulae are given below:
Perimeter of a rectangle = 2 × (length + breadth)
Perimeter of a square = 4 × length of its side
Perimeter of an equilateral triangle = 3 × length of a side
Perimeter is the distance covered along the boundary forming a closed figure when you go round the figure once.
Area of a rectangle = length × breadth
Area of a square = side × side
To calculate the area of a figure using a squared paper, the following conventions are adopted:
Ignore portions of the area that are less than half a square.
If more than half a square is in a region. Count it as one square.
If exactly half the square is counted, take its area as 1/2 sq units.

### The lid of a rectangular box of sides 40 cm by 10 cm is sealed all round with tape. What is the length of the tape required?

Total length of tape required
= Perimeter of rectangle
= 2 (40 + 10)
= 2 x 50
= 100 cm
= 1 m

Thus, the total length of tape required is 100 cm or 1 m.

### A table-top measures 2 m 25 cm by 1 m 50 cm. What is the perimeter of the table-top?

Length of table top = 2 m 25 cm = 2.25 m
Breadth of table top = 1 m 50 cm = 1.50 m
Perimeter of table top
= 2 x (length + breadth)
= 2 x (2.25 + 1.50)
= 2 x 3.75
= 7.50 m

Thus, the perimeter of table top is 7.5 m.

### Find the perimeter of a triangle with sides measuring 10 cm, 14 cm and 15 cm.

Perimeter of triangle = Sum of all three sides
= 10 cm + 14 cm + 15 cm = 39 cm
Thus, the perimeter of triangle is 39 cm.

### Find the perimeter of a regular hexagon with each side measuring 8 cm.

Perimeter of Hexagon = 6 x length of one side = 6 x 8 m = 48 m
Thus, the perimeter of hexagon is 48 m.

### Find the cost of fencing a square park of side 250 m at the rate of ₹20 per meter.

Side of square = 250 m
Perimeter of square = 4 x side = 4 x 250 = 1000 m
Since, cost of fencing of per meter = ₹ 20
Therefore, the cost of fencing of 1000 meters = 20 x 1000 = ₹20,000

### A table-top measures 2 m by 1 m 50 cm. What is its area in square meters?

Length of table = 2 m
Breadth of table = 1 m 50 cm = 1.50 m
Area of table = length x breadth = 2 m x 1.50 m = 3 m²

### Five square flower beds each of sides 1 m are dug on a piece of land 5 m long and 4 m wide. What is the area of the remaining part of the land?

Side of square bed = 1 m
Area of square bed = side x side = 1 m x 1 m = 1 m²
Area of 5 square beds = 1 x 5 = 5 m²
Now, Length of land = 5 m
Breadth of land = 4 m
Area of land = length x breadth = 5 m x 4 m = 20 m²

Area of remaining part
= Area of land – Area of 5 flower beds = 20 m² – 5 m² = 15 m²
