Answer 1

QUESTION:–

A rectangular piece of land measures 0.8 km by 0.6 km. Each side is to be fenced with 4 rows of wires. what is the length of the wire needed.

GIVEN:–

LENGTH=0.8KM

BREADTH=0.6KM

Each side is to be fenced with 4 rows of wires.

FIND:–

What is the length of the wire needed.

SOLUTION:–

PERIMETER OF THE LAND.

2(L+B)

=2(0.8+0.6)KM

=(2×1.4)KM

=2.8KM

THEREFORE,

LENGTH OF WIRE.

(2.8×4)KM

=11.2KM

ANSWER:–

11.2KM

Answer 2

Given:

A rectangular peice of land with

• Length = 0.8 km
• Breadth = 0.6 km

And its need to be fenced with

• 4 rows of wires

What To Find:

The length of the wire needed​.

How To Find:

To find the length of wire needed we will first find the perimeter of the rectangular peice and then after finding the we will multiply the perimeter with 4 row of wires.

Solution:

Using the formula,

⇒ Perimeter = 2(length + breadth)

Substitute the values,

⇒ Perimeter = 2(0.8 + 0.6)

Solve the brackets,

⇒ Perimeter = 2(1.4)

Multiply 2 by 1.4 ,

⇒ Perimeter = 2.8 km

Now finding the length of the wire,

⇒ Length of the wire = 4 × Perimeter

Substitute the value,

⇒ Length of the wire = 4 × 2.8 km

Multiply 4 by 2.8 km,

⇒ Length of the wire = 11.2 km

∴ Therefore, the length of the wire is 11.2 km.
