Introduction

In this article, we will explore the relationship between the perimeter and area of a rectangular ground. We will also delve into the roots of a quadratic equation and use this knowledge to find the length and breadth of the given ground. Additionally, we will discuss how many pieces of land can be made with the given ground.

The Perimeter and Area of a Rectangular Ground

The perimeter of a rectangle is given by the formula $2(l + b)$ , where $l$ is the length and $b$ is the breadth. The area of a rectangle is given by the formula $lb$ . In this problem, we are given that the perimeter of the rectangular ground is 66 m and the area is 260 sq. m.

Formula for Perimeter and Area

The formula for the perimeter of a rectangle is:

Perimeter = 2(l + b)

The formula for the area of a rectangle is:

Area = lb

Given Values

We are given that the perimeter of the rectangular ground is 66 m and the area is 260 sq. m.

Perimeter = 66 m Area = 260 sq. m

The Roots of a Quadratic Equation

A quadratic equation is a polynomial equation of degree two, which means the highest power of the variable is two. The general form of a quadratic equation is $ax^2 + bx + c = 0$ , where $a$ , $b$ , and $c$ are constants, and $a \neq 0$ . The roots of a quadratic equation are the values of $x$ that satisfy the equation.

Formula for Roots

The roots of a quadratic equation can be found using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

Illustration of Roots

To illustrate the roots of a quadratic equation, let's consider the equation $x^2 + 4x + 4 = 0$ . We can factor this equation as $(x + 2)^2 = 0$ . This means that the only root of this equation is $x = -2$ .

Finding the Length and Breadth of the Given Ground

Now that we have discussed the perimeter and area of a rectangular ground and the roots of a quadratic equation, we can use this knowledge to find the length and breadth of the given ground.

Using the Perimeter Formula

We are given that the perimeter of the rectangular ground is 66 m. We can use the perimeter formula to write an equation:

2(l + b) = 66

Using the Area Formula

We are also given that the area of the rectangular ground is 260 sq. m. We can use the area formula to write another equation:

lb = 260

Solving the Equations

We can solve these two equations simultaneously to find the values of $l$ and $b$ .

2(l + b) = 66 lb = 260

Solution

Solving these equations, we get:

l = 20 m b = 13 m

How Many Pieces of Land Can Be Made with the Given Ground

Now that we have found the length and breadth of the given ground, we can use this knowledge to determine how many pieces of land can be made with the given ground.

Dividing the Ground

We can divide the ground into smaller pieces by drawing lines parallel to the length and breadth of the ground. Let's assume that we want to divide the ground into $n$ pieces.

Formula for Number of Pieces

The number of pieces of land that can be made with the given ground is given by the formula:

Number of Pieces = (l + b) / n

Substituting Values

We can substitute the values of $l$ and $b$ into this formula:

Number of Pieces = (20 + 13) / n Number of Pieces = 33 / n

Finding the Value of n

To find the value of $n$ , we need to know the total area of the ground. We are given that the area of the ground is 260 sq. m. We can use this information to find the value of $n$ .

Formula for Area

The area of the ground is given by the formula:

Area = lb 260 = 20 × 13

Finding the Value of n

We can rearrange this equation to solve for $n$ :

n = 260 / (20 × 13) n = 260 / 260 n = 1
