Question

A rectangular piece of land measure 0.7 km by
0.5 km. Each side is to be fenced with your of
wires. What is the length of the wire needed?​

Answer 1

Answer:

pls mark me brainliest

Step-by-step explanation:

The perimeter of a rectangular piece of land = 2(Length + Breadth)

= 2(0.7+0.5)

= 2(1.2)

= 2.4 km

\because1km\ =\ 1000m∵1km = 1000m

\therefore0.24\ =\ 1000\times0.24=2400∴0.24 = 1000×0.24=2400 m.

Since 4 rows of wire is required.

\therefore2400\times4=9600∴2400×4=9600 m.

\therefore9600\ m\ =\ 9.6\ km∴9600 m = 9.6 km

Therefore, length of wire required is 9.6 km or 9600 m.

Answer 2

Correct Question:

• A rectangular piece of land measure 0.7 km by 0.5 km. Each side is to be fenced with 4 rows wires. What is the length of the wire needed?

Answer :

• 9.6 km is the length of the wire needed

Given :

• Length = 0.7 km
• Breadth = 0.5 km
• Each side is to be fenced with 4 rows of wires

To find :

• What is the length of wire needed

Solution :

As we know that ,

• Perimeter of rectangle = 2(length + breadth)

where , length is 0.7km and breadth is 0.5km

》 2(length + breadth)

》 2(0.7 + 0.5)

》 2(1.2)

》 2 × 12/10

》 2.4km

According To Question Given that , 4 rows of wires then ,

We need to find the length of wire needed so ,

• Length of wire needed = 4 × Perimeter land

》 4 × 2.4

》 4 × 24/10

》 96/10

》 9.6km

Hence , 9.6 km is the length of the wire needed
