Step 1: Find the perimeter of the square

$$\text{Perimeter}=4\times \text{side}=4\times 50=200\text{ meters}$$

Step 2: Calculate total fencing cost

$$\text{Cost}=200\times 8=\text{Rs. }1600$$

Explanation

In Maths, a straight angle is an angle equal to 180°.

It is called straight because it appears as a straight line.

Explanation

an isosceles triangle has equal in sides and in equal angle

Explanation

As we all know

Circumference of the circle: 2πr

The radius of the circle: r

Ratio = 2πr : r = 2πr/r = 2π

Thus we conclude that 2π:1

Explanation

A sequence is arithmetic if the common difference of all terms of a sequence is the same.

A sequence is geometric if the common ratio of all terms of sequence is the same.

A common difference is the difference between consecutive numbers in an arithmetic sequence

Sh14-8-2023

Explanation

 The formula for the nth term of an arithmetic sequence is aₙ = a₁ + (n - 1)d, where: 

aₙ is the nth term of the sequence

a₁ is the first term of the sequence

n is the term number (e.g., 1st term, 2nd term, etc.)

d is the common difference between consecutive terms

For example, if the first term (a₁) is 2 and the common difference (d) is 3, then the 5th term (a₅) would be calculated as follows: 

a₅ = 2 + (5 - 1)3 = 2 + 4 * 3 = 2 + 12 = 14 

Explanation

The area of a rectangle is calculated by multiplying its length by its breadth:

Area = Length × Breadth

= 16 cm × 3 cm

= 48 cm²

Explanation

To find the area of the strip:

1. Calculate the area of the larger rectangle (including the strip):

New length = 82 + 2_4 = 90 cm

New width = 75 + 2_4 = 83 cm

Area of larger rectangle = 90 * 83 = 7470 cm²

2. Calculate the area of the original rectangle:

Area = 82 * 75 = 6150 cm²

3. Find the area of the strip:

Area of strip = Area of larger rectangle - Area of original rectangle

= 7470 - 6150

= 1320 cm²

Explanation

A trapezium (also called a trapezoid in some regions) has only one pair of parallel sides.

The other two sides are not parallel, distinguishing it from other quadrilaterals like parallelograms or rhombuses.
