Question

- If the total length of the wire required for fencing the ground is 630m. Form a linear equation, if the length of the
ground is "metres"

Answer 1

Answer :-

Length + Breadth = 315 m

Step-by-step explanation :-

Let us consider the ground to be in the form of a rectangle.

Fencing a ground covers only the outer part of the field and not the inner portion.

So length of wire required for fencing the ground would be the perimeter of that field.

Perimeter = Length of wire required

⇒ Perimeter = 630 m

We know that

Perimeter of rectangle = 2 (Length + Breadth)

Let

• Length be ‘l’
• Breadth be ‘b’

Substitute in the above equation

⇒ 2 (l + b) = 630 m

⇒ l + b = 630 ÷ 2

⇒ l + b = 315

∴ The linear equation would be ⟨l + b = 315⟩

Answer 2

Step-by-step explanation:

Let us consider the ground to be in the

form of a rectangle.

Fencing a ground covers only the outer

part of the field and not the inner portion.

So length of wire required for fencing the

ground would be the perimeter of that

field.

Perimeter = Length of wire required

Perimeter = 630 m

We know that

Perimeter of rectangle = 2 (Length +

Breadth)

Let

• Length be 'I'

Breadth be 'b'Substitute in the above equation

2 (1 + b) = 630 m

⇒ 1 + b = 630 ÷ 2

→ 1 + b = 315

..The linear equation would be (1 + b =

315)
