Question

The Kulas have decided to enclose their rectangular garden. The length of the garden is 6 ​meters, and 20 meters of fencing is needed to enclose the garden. What is the width of the​ garden? what is the length

Answer 1

Answer:

• Width of the garden is 4 m.

Step-by-step explanation:

Given that:

• Length of a garden is 6 metres.
• Length of fencing needed to enclose the garden is 20 metres.

To Find:

• Width of the garden.

As we know that:

Perimeter of rectangle = 2(l + b)

Where,

• l = Length of the rectangle
• b = Breadth of the rectangle

As,

• Length of fencing = Perimeter

Therefore,

• Perimeter of the garden = 20 m

Let us assume:

• Width of the garden be x.

Substituting the values,

2(6 + x) = 20

Opening the bracket,

12 + 2x = 20

Transposing 12 from LHS to RHS and changing its sign,

2x = 20 - 12

Subtracting the numbers,

2x = 8

Transposing 2 from LHS to RHS and changing its sign,

x = 8/2

Dividing 8 by 2,

x = 4

Hence,

• x = 4

Therefore,

• Width of the garden is 4 m.
